I stumbled upon this thread when I decided to try my Baycom BP-1 modem
with linux. Nobody has stated which Baycom modem they are talking about
so this might not apply to all Baycoms. I bought my BP-1 in 1991 so this
problem may have been addressed in later modems.

I am running kernel 2.0.33 with no patches (Slackware 3.3 package) if
that matters.

My problem is this: Somewhere along the line the Baypac group chose to
use non-standard pinouts at the rs232 interface. They use the
Terminal-Ready lead to transmit data rather than the normal Transmit-Data
lead and they bring out the received data on the Clear-To-Send lead rather
than the Receive-Data lead! Since the ax25 programs in linux use the
normal leads the two do not mix. The BP-1 uses the Request-To-Send lead
to key the transmitter but the linux programs apparently do not.
What would it take to make call et al turn on the Request-To-Send lead
when they want to transmit?

Thanks
