+===== TXTAIL note =====
+Fun finding. Nino implemented TXTAIL support in April, to support a newer Icom with digital audio chain with latency. It seems that BPQ sends a TXTAIL KISS command with value 3 (30ms) by default. My 70cm 9k6 port has therefore had a 30ms tail since then. That's a ton of overhead at 9k6!  TXTAIL=0 in the port config seems to result in BPQ still sending 3 (30ms) to the modem periodically. But TXTAIL=1 (ms) in the config seems to result in BPQ sending TAIL KISS command with value 0 (0ms) which is what we probably want. Therefore my recommendation is to put TXTAIL=1 into the PORT config for any NinoTNC port that isn't an Icom 9700.
