I mentioned earlier (I think!) that I'm using a TNC-X in my setup. I got a couple reports that my station wasn't connecting. I've used this same TNC-X for some basic keyboard-to-keyboard packet so I know it works. And it works on Winlink Express for basic email. But, as I watched it running under RMS Packet, it never appeared to transmit. After 24 hours of that nonsense I decided to try a KPC-3+ in it's place. The TNC had all necessary cables still connected from the last time I had used it so swapping the two TNCs was a no-brainer.
