I reacted to soon... my serial port is based on an 16550A.
But i find it strange that the 16550A is mentioned in the baycom.c
source file.

I'm using a SoundBlaster AWE64 but i think this should work with any
SoundBlaster 16+.
The script i use the start the soundmodem is. But this only works (i
think) if you compile
the soundblaster driver as a module.

#!/bin/sh
#
# Set Soundmodem Parameters
#

setcrystal -s 0x220 -i 5 -d 1

# Select driver for interface sm0
sethdlc -p -i sm0 mode sbc:afsk1200 io 0x220 irq 5 dma 1 serio 0x2f8

# Interface sm0 up
ifconfig sm0 up

# Set call for interface sm0
axparms -setcall sm0 PE1RXS-1

For some other files see my previous mail.

Thanx for the info, i have to run now.
