[OZAPRS] HF APRS with linux soundmodem.

[stevez at tpg.com.au]

Hello Ray,

I'm pretty sure those files are not relevant for the modem to work. They
are used to help the ax25tools toolset do their thing.
My problem is that I can't even decode packets. I'm not even attempting
to use any applications - just looking at the output from
/dev/soundmodem0 !.

Anyway, since you asked, see below for /etc/ax25/axports. I have no
instance of rc.ax25 on any of my systems.
# /etc/ax25/axports
#
# The format of this file is:
#
# name callsign speed paclen window description
#
1       OH2BNS-1        1200    255     2       144.675 MHz (1200  bps)
2       OH2BNS-9        38400   255     7       TNOS/Linux  (38400 bps)


As you can see, I've never even touched the above file. I don't use any
of the ax25tools such as "call", etc.

Thanks,

Steve.
