I finally decided I was sick of 1200 baud, and wanted to use the
soundmodem driver to speed things up a bit. So far, so good, I spent the
morning getting the afsk1200 talking to my existing station, but do have a
couple of problems that arose. I keep thinking I've seen these come up
before, but I can't find them in the archives anywhere, so here goes...
The system is a P-166 w/ Red Hat 6.1 and the latest three ax25 packages
(lib, tools, apps). Everything compiled perfectly, and I configured the
files in /etc/ax25. (I compiled the three packages to use the old
locations.)
I was able to get the audio portion working immediately, and proceeded to
try to get the PTT going. I first tried to use a serial port, but have so
far been totally unable to get the RTS or TxD to toggle. I reconfigured to
use the parallel port, and it immediately worked. Is there something
else I need to do to get the serial port working? The ports are properly
configured for ttyS0 and ttyS1, standard I/O and IRQs. Nothing else is
using them, no gettys or anything. If I fire up minicom, using hardware
flow control RTS toggles nicely so I know the hardware works. (These
are on-motherboard serial ports if it matters...) The parallel port will
work for now, but I would sure like to free it up!
And what happened to smdiag? After installing the utils I have smmixer,
sethdlc, so forth but no smdiag... I was able thru trial and error to get
the audio levels right at 1200, but I expect the higher baud rates will
require more accurate level adjustments...
Thanks,
