Just an extra thought or two Dean

Have you tried setting up soundmodem or a vanilla TNC with the same box?
Thinking in terms of checking that AX25 is working in the kernel properly.

And grabbing at straws.....

I wonder if "baycom-com2" can be a real valid port name. Mine have
always been real short names like "radio".

Is 300ms long enough TXD for your TX?

Is the PK232 DCD only based on audio present (unsquelched) or has it
detected a valid set of tones? (ie soft DCD)

And rather than using "call" also try and ping a box in the interface
subnet and monitoring the activity on the other PC (say 192.168.10.11).
I can never remember whether connect mode (ie "call") runs on top of the
IP interface or at a layer beneath...

I also copy/pasted this from the baycom website;

During the last three months we have been reported some problems with
RS-232 cards using the fast 16550 chips with internal FIFO instead of
the "traditional" 8250 chip. There seems to be a number of 16550
versions (not all of them!) which do not support the internal 6 bit mode
of the RS-232 we use for clock and baudrate generation in the BayCom
terminal. This mode is rarely needed for other applications and it looks
like chip designers have not implemented it on these chips.
As a consequence, BayCom will not run on these PCs. Unfortunately, there
is no easy workaround, so we could not solve this problem yet. We will
try to fix it with the next version.
If you run into trouble, buy a simple 8250 card for 10 US$ and put it
into your PC as COM3/COM4 and configure BayCom on it. Make sure, that
addresses AND interrupts are set properly as configured in the INSTALL
program.

We would have some interest to know, which of the 16550 do not run.
Currently, National Semiconductors are the only one's known to us. If
you have a trouble making card, please mail the name of the manufacturer
of the card and of the 16550 chip on the card to .

Have you tried telling setserial uart 8250?

Tom Sailer has answered a few queries of mine directly so that may be
another avenue. His personal website and email contact are on the baycom
website.

Last time I was running packet I actually used the soundmodem suite.
Almost got all fired up using Q15X25... (2500bps)
