Hi Chris,
I am too experiencing this, but I have issues with JNOS hanging with a hardware TNC too.
This is off-topic for the direwolf group, but there is a well known (for everybody except Kantronics who deny it) problem with the KPC-3/KPC-3+ firmware in KISS mode (and JNOS interfaces with the TNC in kiss mode). At some point (sooner or later depending on the traffic volume) the KPC-3(+) will gets its buffer pointers messed up and from that point forward will pass on the contents of the oldest still buffered packet whenever a new packet comes in. In connection-less operation (e.g. APRS) this results in some messages being duplicated and others being strangely delayed. In connected mode operation (e.g. BBS access) this plays complete havoc and prevents normal operation until the KPC-3(+) is being reset (either power-cycle or taken out of KISS mode and then KISS mode turned back on which involves a soft reset).
On 15 KPC-3+ TNCs (4 JNOS BBS, 3 Radios each) we experience this issue about once every 1-2 month.
As for the hangs I had with DireWolf 1.7, I repeated the same test 4 times with DireWolf 1.6 and cannot reproduce it. I'll try to repeat the test with DireWolf 1.7 (this time with logging enabled) hopefully later this week.
Thanks
