The AMSG command switches you into "APRS Messaging" mode, enabling you
to exchange messages and bulletins with APRS and UI-View users.
Syntax is "AM[sg] <port>", where <port> is the number of the radio
port on which traffic will be sent and received. e.g. "AM 13" will use
port 13.
APRS Messaging mode has it's own help system.

The ANSI command switches ANSI colour mode on/off, and reports the
current mode. It may be shortened to "AN".
    Syntax: AN[si] [on | off]
    Examples: ANSI          Reports current on / off state.
              ANSI ON       Turn colour on.
To use ANSI colour, you need an ANSI-capable terminal, such as
XRouter, or Windows / Linux Telnet.

The ARP command displays the ARP (Address Resolution Protocol) table, 
which is used to make decisions about how to route IP datagrams.

Blog commands are as follows (31 lines):
B[ye]       Returns you to the node (same as Q[uit]).
C[reate]    Begins the creation of a blog article (sysop-only).
D[elete]    Deletes an article or reply that you have entered.
H[elp]      Displays a help summary.
LIK[e] [n]  (shortcut "K") is used to "like" either the article you've
            just read, or article number "n".
L[ist]      Displays or re-displays the header information of up to 5
            articles at a time. Headers are displayed in reverse
            chronological order, i.e. the most recent at the top.
N[ewer]     Displays up to 5 newer articles, i.e. forward in time.
O[lder]     Displays up to 5 older articles, i.e. back in time.
Q[uit]      Returns you to the node (same as B[ye].
R[ead] n    Reads article number "n".
REP[ly] [n] (shortcut "Y") begins a reply to the article you've just
            read, or to article number "n".
V[iew]      View replies to an article.
Type "H BLOG" for information about the blog.

The BLOG command connects you to the sysop's blog, either at this
node, or at another XRouter.
    Syntax: BL[og] [nodecall | nodealias]
The blog is a text-only, packet radio version of a "web log". It is a
space for sysops to post "articles", which other people can "like" or
reply to.
Only SYSOPS can create original articles, but anyone may add comments
to an existing article. Comments are not restricted in size.
Type "H BLOGCMDS" for information on the blog commands.

The "BYE" command, which can be abbreviated to "B" disconnects you 
from XRouter and terminates all dependent sessions.
This is useful when you do not have easy access to a TNC's "command 
mode", or when you have uplinked from another node with the "stay" 
option enabled.

The CHAT command connects you to the chat server, either at this node,
or at another XRouter of your choice, allowing you to conduct
conferences with one or more other users..
    Syntax: CH[at] [nodecall | nodealias]
There are 65536 separate channels (or "rooms") of which the first 256
(*except room 101) are local to this system, and the remainder are
linked to other systems, allowing widely separated users to chat.
(*Room 101 links to RoundTable/BPQ chat, if sysop has configured it.)
The chat server may also be reached by connecting to its own callsign,
either directly or through the Netrom network, or by telnetting to
tcp port 3600 (if the sysop has enabled it).
Further help may be obtained from the chat server's own help system.

The CONNECT command, which may be abbreviated to "C", instructs the 
node to make an outgoing (downlink) AX25 level 2 or 4 connection 
with another system.
If the target is a known node (i.e. one which is in the nodes table) a 
port number is not required, and will be ignored if supplied.  The 
node will attempt to make a level 4 connection with the target, 
using information from the routing tables.  However, a level 2 
connection with an immediately adjacent node may be forced, either by
using  the target's alias with an arbitrary SSID, specifying a port
number if required (e.g. C 4 MLVN-1), ot by prefixing the target's
nodecall with an exclamation mark (e.g. C 4 !G4FPV)
If the target is an XRouter, and it is in the nodes table, adding a
"service number" after the nodecall or alias, e.g. "C kidder 2",
connects you to that service, in this example the target's PMS. Type
"H SERVICES" for a list of XRouter's "standard services".
If the target is not a known node, XRouter will attempt to make a 
level 2 connection.  On multi-port systems, a port number must be 
specified.
The "V" (via) parameter allows up to 7 digipeaters to be specified, 
e.g.:  "C 3 G6YAK V G8NTU G8EPR"
The "S" (stay) parameter, e.g. "C <nodecall> S" causes the uplink 
session to stay connected when the downlink session to the target node 
is terminated.

The CQ command can only be used in LISTEN mode. It sends a CQ message
onto the frequency you are LISTENing on. Optional text and digipeater
path may be supplied.
    Syntax: CQ [v[ia] digi,digi...] [text]
The digipeater string, if included, must not include any spaces.
    Examples: CQ
              CQ Parks on the air
              CQ v g8pzt,m0wof Gloucester Docks
The message is sent only once, but you may repeat the command at
suitable intervals.
    See also: LISTEN - Invoke Listen mode.

The DATE reports the system date at this node.
Syntax is simply "D[ate]".

The DX command displays a list of the most distant APRS stations heard
by XRouter, along with their positions, distances and headings.
    Syntax: DX [port]
If the optional port number is given, e.g. "DX 13", only the stations
received on that port will be shown.
Whether or not the DX list records digipeated stations depends on how
the sysop has configured it.  If included, digipeated stations are
clearly identifiable by an entry in the "Via" field, which is blank
for directly heard stations.
If the sysop hasn't bothered to define the router's position, no DX
information will be available - lobby your sysop!

The ECHO command starts an echo session, in which anything you type
is echoed back to you.  This has little use, except for link testing.
An echo session can be terminated either by typing "/x" on a new line,
or simply by disconnecting.

The "FINGER" command display information about users of this and other 
systems.
    Syntax: FINGER <user | user@host | @host>
If the command is of the form "FINGER <user>", where <user> may be a 
callsign or other "handle" the router displays any information it has 
on that local user.
If the form "user@host" or "@host" is used, XRouter will attempt to 
resolve "host" into an IP address and establish a contact with 
the finger server on that host.
e.g. FINGER g8pzt          - Info on local user g8pzt
     FINGER g8jvm@iptlfd   - Info on user of another system

The GPING command sends a GCMP echo request to the specified target.
    Syntax: GP[ing] <addr> [len [sec]]
If the target understands the protocol it will return a reply,
allowing the number of hops and the round trip time to be estimated.
It is mainly of use as a network diagnostic.
Examples: GPING 131.91.2.1           Single ping of minimum size
          GPING 131.91.2.1 50        Single ping with 50 bytes data
          GPING 131.91.2.1 512 10    Ping 512 bytes every 10 secs
If no reply is received, either the target doesn't understand the
protocol, or hasn't been configured for GNET, or is currently
unreachable, or the ping was "lost" in transit.

The GTRACERT commmand traces the route to a Globalnet host.
    Syntax:  GT[racert] <addr> [maxhops [maxwait(ms)]]
    <addr> is the Globalnet address of the target host.
           (this is a dotted quad, but is NOT an IP address)
    [maxhops] is the maximum number of hops to trace (default 30).
    [maxwait] is the maximum time to wait for a reply from each
              router. The default is 4 seconds.
The only mandatory parameter is <addr>. 
Examples:  
    GT 87.127.21.3       - Trace 87.127.21.3 with default parameters.
    GT 44.141.91.2 10    - Trace 44.131.91.2 to a max of 10 hops.
    GT 87.127.21.3 5 20  - Trace 87.127.21.3, 5 hops, max 20secs.

The HELP command, which may be abbreviated to "H", displays help for 
commands and other topics.
    Syntax: HELP [cmd | topic]
If no arguments are given, a short text gives directions on how to 
access help.
If the argument is a topic or a command name, the help file for that 
command or topic is displayed.  The argument "*" will list all the 
help topics available.
Examples:  H *      - List available help topics.
           H PING   - Gives help for PING command.

The "@" command is used by remote sysops to request and answer 
the password challenge, in order to gain full sysop status.
If you enter "@" alone, the system replies with a matrix consisting of 
5 lines of 5 numbers. 
You must then choose ONE of the lines, and send the "@" command again, followed by the 5 characters from the password string which correspond to the 5 numbers on the chosen line.  
There must be a space after the "@" but no spaces between the
characters.

The HOST command displays information about a TCP/IP host, and is used
mainly for looking up a hostname from an IP address or vice versa.
   Syntax: HO[st] <hostname> | <ip_address>
   Examples: HO kidder.ampr.org
             HO 44.131.91.245
The quality of the information returned depends on how the sysop has
configured the router and whether or not an external DNS can be
reached.

The INFO command, which may be abbreviated to "I", displays
information about the node and other topics chosen by the sysop. It
can also display information from other XRouter nodes.
    Syntax: I[NFO] [topic | nodecall | nodealias]
If you use "I" alone, some information about the node should be
displayed, if the sysop has set it up.
The command "I[nfo] PAGE" always provides a summary of the node info
If you send "I *", the available info topics are listed, and you can 
read one by sending "I" followed by a space, then the topic.
If the command's argument is the callsign or alias of another XRouter
that is in this node's table, a summary of information about that
node is displayed.
Examples: I FOURPAK   - Displays information about the FOURPAK group.
          I G8PZT     - Displays info summary from node G8PZT

The IP sub-commands are used to display and alter the contents of the 
table responsible for routing of IP datagrams.
The only one available to non-sysops is "IPR[outes]", which displays
the IP routing for amprnet data only.
"Len" is the number of bits (left to right) of the address which are
matched by the routing entry.
"Gateway" is where datagrams are sent, if not direct. "0.0.0.0"
denotes a direct route.
"Mode" has many variants, the most common is "d" (datagram).
A non-zero "Timer" denotes a temporary (learned) entry.
Sysops should consult the MAN page for the IP command.

The IPROUTE command, which may be abbreviated to IPR, displays the 
contents of the table responsible for routing of IP datagrams.
For each route it displays the IP address, the subnet mask, the 
gateway address, the port and the mode (Datagram, VC or Netrom).
"Len" is the number of bits (left to right) of the address which are
matched by the routing entry.
"Gateway" is where datagrams are sent, if not direct. "0.0.0.0"
denotes a direct route.
"Mode" has many variants, the most common is "d" (datagram).
A non-zero "Timer" denotes a temporary (learned) entry.

The J (jlist) command lists the callsigns of the last 20 stations who
connected to the node, with the most recent shown first.

The L4LINKS command shows information about the NetRom Layer 4 links
currently originating or termnating at this node.
    Syntax: L4[links]
The display is like this:
Local    Cct  Remote   @Host    Cct  S Txq Rxq  Rtt Tr T/o Con Cho Ack
G8PZT-9  0001 G8PZT-8  G8PZT-8  1253 2   0   0  288  0 120 121   0   0
"Local" and "Remote" are the "user" callsigns.
"Host" is the other end's node callsign.
"Cct" is the circuit number.
"S" is the link state.
"Txq" is the number of frames queued for transmission.
"Rxq" is the number of frames queued in the receiver.
"Rtt" is the average Round Trip Time in milliseconds.
"Tr" is the number of retries.
"T/o" is the L4T1 interval in seconds.
"Con" is the remaining connection timer interval in seconds.
"Cho" is the remaining choke timer interval in seconds.
"Ack" is theremaining ack timer interval in seconds. 

The LANG command shows the available languages, reports the
current language, and allows the language to be changed.
    Syntax: LA[ng] [en | fr | es | nl]
Only English (en), French (fr), Spanish (es) and Dutch (nl) are
available at present. More languages can be added upon request.

The LINKS command lists the AX25 layer 2 links originating or
terminating at this node.
It shows the callsigns being used at both ends of the link plus some
other data, such as frame counts and retry rates.

The LISTEN command, which can be abbreviated to "LIS", initiates
"listen mode" on a specified PORT.
In this mode you are able to "monitor" traffic on the chosen port,
and the node will accept incoming connections to your callsign.
    Syntax: LIS[ten] <portnum> [0]
Non-sysops may only listen on RADIO ports, and you can not listen on
the port which you are using to connect to the node. All the normal
node commands are available in this mode.
Traffic monitoring is enabled by default, but may be disabled by
supplying 0 (zero) as an optional additional argument. 
In listen mode, you may use the CQ command to advertise your presence.
Your SSID is inverted in the usual Net/Rom way, so if you are
connected to the node as G9XYZ, you will be listening and
broadcasting as G9XYZ-15.
To exit listen mode use "LISTEN 0" or "LISTEN OFF"
    See Also: CQ    - Call CQ whilst in listen mode.
              WATCH - Monitor traffic on port(s).

The MAN command is used to access the online sysop's manual, which
is a collection of pages, each covering a different command or
topic. The MAN pages are designed for sysop use, and are not
available to non-sysops.
   Syntax: MAN [command | topic]
   Example: MAN ARP  -- Display manual page for ARP command.
Entering MAN alone displays a list of available pages.
To read a specific page enter MAN followed by the command or topic
for which you require help.
The manual is divided into several sections, usually indicated in
parentheses after the command name, e.g. ARP(1).  Section 1 is the 
command reference section.

If the facility is enabled on the specified port, the MHEARD command 
lists the most recently heard stations on that port, arranged in
descending time order.
    Syntax: M[heard] <portnum | ALL>
    Examples:  MH 4     - Lists stations recently heard on port 4
               MH ALL   - Lists stations recently heard on any port
Each entry shows the date / time of last reception, and the total
number of frames heard from that station.
If the station was digipeated, the digipeater's callsign is shown
in the VIA column, and if the station's beacon included an APRS
position, that position is shown, alog with the distance and
direction from this node.
The characters in the TYPE field indicate whether or not the station
is capable of (D)igipeating, (N)etrom, (I)P or (A)RP.

The NFTP command is for sysops to exchange files between nodes, but
can also be used to exchange files between non-sysops and the node.
    Syntax: NF[tp] <nodecall>
In "non-sysop" mode <nodecall> MUST be the callsign or alias of the
node itself.
Upon successful connection, the user is granted access to a "public"
files area, which he can use to upload and download files using fairly
standard FTP server commands, such as HELP, LIST, STOR, RETR etc.

The NODES command, usually abbreviated to "N", displays the contents 
of the NetRom nodes table, showing which NetRom (but not KA) nodes are
known to the system.
Syntax: N[odes] [ <nodecall> |  * | > | < | + | A[dd] | B (y)
        | C (all) | D[rop] | F (rames) | H (ops) | HE[lp] | I (paddr)
        | N (etrom) | O (bsolete) | P (osition) | Q (ueue) | R (tt)
        | S (tats) | T (imes) | V (ia)] 
N by itself lists all the nodes except "hidden" nodes whose alias 
begins with the hash (#) character. "N *" includes the hidden ones.
If the argument is a known node call / alias e.g. "N MLVN" (wildcards
are accepted), the preferred route to the specified node, and up to
two alternative routes are displayed.  A chevron ">" in the left-most
column indicates the currently active route.  The first number shows
the overall path quality to the target node, the second is the 
"obsolescence count", and the third number is the port number.
For explanation of the other options type "N HELP"

The NPING command sends an echo request to the specified target via
the Netrom network. If the target understands the protocol it returns
a reply, allowing the number of hops and the round trip time to be
estimated. It is mainly of use as a network diagnostic.
   Syntax: NP[ing] <callsign | alias> [bytes [secs]] 
   Examples: NP GB7GC          Ping once with 0 byte payload.
             NP GLOS 100       Ping once with 100 byte payload.
             NP GLOS 50 30     Ping every 30 secs with 50 byte payload.
If no reply is received, either the target doesn't understand the
protocol, or is currently unreachable, or the ping was "lost" in
transit.

The NRR command sends a "record route" packet to the specified netrom
target system.  If the target understands the protocol it will return
a reply, allowing the path taken to be shown.  Each NRR-capable node
along the path inserts its own call into the packet.
   Syntax:    NRR <callsign | alias>
   Examples:  NRR GB7GC
              NRR FOD
If no reply is received, either the target doesn't understand the
protocol or the request or reply were lost in transit.  If the reply
contains only "?" in place of each callsign, it means there were no
NRR-capable nodes en-route to/from the target.
NRR is correctly handled by XR32, XRouter, (X)Net
NRR is not understood by: FPAC, TNOS, JNOS
NRR is not returned by: BPQ or LinuxNode 0.3.2

The NTRACERT (Netrom TraceRoute) commmand traces the route to a
NetRom node.
    Syntax: NT[racert] <node> [maxhops [maxwait(ms)]]
    <node>    is the callsign or alias of the target node.
    [maxhops] is the maximum number of hops to trace (default 30).
    [maxwait] is the maximum time to wait for a reply from each
              node. The default is 4 seconds.
The only mandatory parameter is <node>. 
Examples:  
        NT VA2OM       - Trace to VA2OM with default parameters.
        NT G7VJA-5 10  - Trace to G7VJA-5 to a max of 10 hops.
        NT XBAL 5 20   - Trace to XBAL, 5 hops, max 20secs.
At present, only XRouter nodes show in the trace. The operation can be
aborted by sending a blank line.

The PING command sends ICMP echo request(s) to the specified IP 
address or hostname for the purposes of route testing.
    Syntax:  PING <hostname | ipaddr> [length [interval]]
An optional data portion of "length" bytes may be specified, and the 
echo request may optionally be repeated every "interval" seconds.  The 
process aborts if you send an empty line.
If there is a reply it will be displayed.  For repeating pings the 
system displays the number sent/rcvd, the average round trip time in 
milliseconds, and the success rate.
Examples:  PING 44.131.91.2           Single ping of minimum size
           PING 44.131.91.2 50        Single ping with 50 bytes data
           PING gb7pzt                Uses DNS to resolve host.
           PING 44.131.91.2 512 10    Ping 512 bytes every 10 secs

The PMS command connects the you either to this node's PMS (Personal
Message System), or to the PMS on another XRouter.
    Syntax: PM[s] [nodecall | nodealias]
The PMS is a no-frills mailbox similar to the one in a Tiny2 TNC,
allowing you to exchange messages and bulletins with other users, and
with the sysop.
If "PMS" is used on its own, you will be connected to the PMS at this
node.
If the argument is the nodecall or alias of another XRouter which is
in the nodes table (e.g. "PMS KIDDER"), you will be connected to the
PMS of that node instead.
Help for PMS commands is available by typing H at the PMS prompt.
Upon exit from the PMS you will be returned to the node.

The PORTS command, normally abbreviated to "P", lists the available 
port numbers, along with a brief description of each.

The "QUIT" command, which can be abbreviated to "Q" disconnects you 
from the node and terminates all dependent sessions.
This is useful when you do not have easy access to a TNC's "command 
mode", or when you have uplinked from another node with the "stay" 
option enabled.

The ROUTES command, which may be abbreviated to "R", lists the 
immediately adjacent NetRom nodes, i.e. those who can be heard 
directly.
    Syntax: R[outes] [ A[dd] | D[rop]  | L[oad] |  R[etr] |  Q[ual]
                 | T [ime] | X[tra] ] 
            (Add, Drop and Load are sysop-only)
For each neighbour node the display shows the port number, the 
neighbour's callsign, the route quality, and the number of nodes 
accessible through that neighbour.  A chevron (>) in the left-most 
column indicates a route which is in use, and an exclamation mark (!) 
in the right-most column indicates that the data has been "locked in" 
by the sysop.
Additional information is displayed, depending on whch subcommand is
used.

The SEND command sends an unproto (UI) packet on the specified port.
Up to 8 optional digis may be included.
   Syntax: SE[nd] <port> <call> [V digi,digi,..] <text>
   Examples: SEND 1 CQ V G8AKX,G8EPR Meet me on 144.800!
             SE 13 APRS V RELAY,WIDE !5224.00N/00215.00W#PHG361

Modern XRouters support a list of "Standard Services", which can be
directly connected from another XRouter using "C <nodecall> <svcnum>".
These service numbers are the same on all nodes. Those marked with "*"
can easily be used by humans. The remainder may use machine-to-machine
protocols such as HTTP.

The STATS command displays information about the performance of the 
router, such as the uptime, the no. of packets routed, error rates 
etc.
   Syntax: S[stats] [* | L1 | L2 | L3 | L4 | TCP | IP ]
   Examples: S       Display single page synopsis
             S *     Display all stats for all protocol layers
             S IP    Display only the IP-layer stats

The TELNET command allows users to "connect" to other TCP/IP systems, 
using a "shell" account, i.e. the user does not need to be running 
TCP/IP as XR32 handles the translation between TCP/IP and whatever
mode you are using.
    Syntax: TELNET <hostname | ipaddress> [port]
    <host> is the hostname or IP number of the target system.
The optional <port> parameter specifies the desired service on the 
target host.  If not supplied, the default is 23, i.e. the "Telnet"
port. Common port numbers are 21 (FTP), 23 (Telnet), 25 (SMTP), and
87 (TTYLINK).
Examples:  TELNET 44.131.90.6 21   Connect to FTP at 44.131.90.6
           TELNET gb7lgs.ampr.org  Remote login to gb7lgs
           TELNET gb7pzt 25        Connect to SMTP server at gb7pzt

The TIME command reports the local time at this (or another) node.
    Syntax: TI[me] [nodecall]
"TIME" by itself reports this system's local time.
"TIME nodecall" reports the local time and date at nodecall. At
present this feature only works if the remote node is also an XRouter.

The TRACERT commmand traces the route to a TCP/IP host.
    Syntax:  TR[acert] <host> [maxhops [maxwait(ms)]]
    <host>    is the hostname or IP address of the target host.
    [maxhops] is the maximum number of hops to trace (default 30).
    [maxwait] is the maximum time to wait for a reply from each
              router. The default is 4 seconds.
The only required parameter is <host>. 
Examples:  
        TR bbc.co.uk       - Trace bbc.co.uk with default parameters.
        TR 44.141.91.2 10  - Trace 44.131.91.2 to a max of 10 hops.
        TR g8pzt 5 20      - Trace g8pzt.ampr.org, 5 hops, max 20secs.

The TTYLINK commmand allows you to chat directly to TCP/IP users.
    Syntax:  TT[YLINK] <hostname | ipaddress> [port]
This is similar to TELNET, except that the default port number is 87, 
which is reserved for keyboard to keyboard chat.  Other port numbers 
may be specified.
Examples:  TTY 44.131.91.4       - Chat to user of this IP address
           TTY g8pzt             - form if hostname is in domain.sys

The USERS command, usually abbreviated to "U", displays the circuits 
which originate or terminate at this node.  "Through" connections are 
not shown.
Established circuits are shown by <-->  and circuits being set up are 
shown thus:  <~~>.
UPLINK is a connection from a user (who may be located at another 
node) to this node, and DOWNLINK is a connection from this node to a 
user.  Uplink/downlink types may be L2 (ax25 level 2), L4 (ax25 level 
4), TCP (TCP/IP), CON (console), TTY (remote console).

The VERSION command, which may be abbreviated to "V", displays the 
software version, author and compilation date.

Wall commands are as follows:
    [H]elp  [L]ist  [O]lder  [N]ewer  [W]rite  [D]elete  [Q]uit
H[elp]   Displays this message.
L[ist]   Displays or re-displays up to 10 messages at a time. Messages
         are displayed in reverse chronological order, i.e. the most
         recent at the top.
O[lder]  Displays up to 10 older messages, i.e. back in time.
N[ewer]  Displays up to 10 newer messages, i.e. forward in time.
W[rite]  Begins message entry. Messages can be up to 255 characters,
         and are posted upon receipt of a <CR> (carriage return).
D[elete] Deletes a message that you have just entered.
Q[uit]   Returns you to the node.
Type "H WALL" for information about the message wall.

The WALL command connects you to the message "wall" either at this
node or at another XRouter of your choice.
    Syntax: W[all] [nodecall | nodealias]
The "wall" is a public message board / guestbook / notepad, where
anyone can write anything they like. Why not have a go?
Typing "WALL" by itself connects you to the local wall. Typing WALL
followed by the nodecall or alias of another XRouter that is in the
nodes table, For example "WALL KIDDER", connects you to the wall on
that node. 
Type H WALLCMDS for information on the wall commands.

The WATCH command, which can be abbreviated to "WAT", allows you to
monitor packet traffic on one or more of the node's RF ports.
    Syntax: WAT[ch] port[+port..] | [OFF]
Non-sysops may only watch RADIO ports, and you can not watch the port
upon which you are connected to the node. Use "WATCH OFF" to
terminate traffic monitoring.
    Examples: WATCH 3
              WAT 3+5
              WATCH OFF
You may issue the command more than once, to watch additional ports.
All the normal node commands are available whilst in "watch" mode. If
the amount of monitored traffic exceeds the capacity of your uplink
with the node, some traffic may be discarded.
   See Also: LISTEN - Listen for incoming connections.

The WX command is used to display a list of up to 5 local APRS weather
stations, and to display a weather summary from specified stations.
The information displayed includes: date and time of reading, distance
and direction of server, pressure, wind speed and direction, gust
speed, temperature, humidity, and rainfall.
    Syntax: WX [callsign]
If no argument is supplied, the callsigns of the available weather
stations (if any) are displayed.
If the argument is the callsign of one of the stations in the list,
the weather summary from that station will be displayed.
Examples: WX           - Display local APRS weather stations
          WX G6GUH-3   - Display summary from station G6GUH-3

The YELL commmand allows you to page the sysop for a chat.
    Syntax:  Y[ell]
The YELL command pages the sysop by sounding a distinctive bleep and
displaying a message.  If the sysop is available, she may then break
in on your session for a chat.
You should bear in mind that the sysop may be out of earshot or busy,
the sound may be disabled during unsociable hours, or the node may be
located on a remote hilltop!
