You can try:
echo -e “\300\377\300” > /dev/ttyS0
Assuming the baud rate has not changed
out from underneath you on ttyS0. Sometimes
the above command does not "seem" to work
(minicom still doesn't see any command prompt)
until I power-cycle the TNC, then the firmware
banner and command prompt comes right up.

Jim,
my first thought is that the Kam is in KISS mode. Now we need
someone who's Kam savvy to tell you how to tell minicom to get you
out... And then how to get back in. An alternative might be to fire
off the KISS script and see if it then talks to the Kam.

Many thanx, Gerry.... Minicom shows "stuff" coming through at 4800
baud..... The guy that lent the KAM to me said that it was header
info. Do you think that it should be ASCII? I get nothing at 2400
or 9600 baud.
Does minicom set the parameters of the port permanently or only
when minicom is running?
Also, running GPSMan allows setting a number of parameters, but not
the interface speed or configuration. Does XASTIR need to have an
interface selected to communicate with the Rinos and if so, which
one?
Many thanx.............. jt

Fire up a copy of minicom and see if you can talk to the serial
port as a 'regular' user. If not, you can tell the serial port
that you (as a regular user) can access it... We can help with all
the bad ways to do that...

After a disk crash in a laptop, I replaced the hard disk,
reloaded open SUSE 10.2, rebuilt Xastir with all the options
( including GPSMAN), and reloaded all the maps.. I connected a
KAM TNC to the serial port and selected Serial TNC in the
interface control. I have tried a variety of TNC port
identifiers ( /dev/ttyS0, COM1, etc.) and tried "tnc-startup.kam"
as well as "tnc-startup.sys". Checking the Incoming data window
when I turn the KAM on and off yields nothing. I also tried
using a USB to serial converter with the same null result.
When I connect the laptop to the internet, I can see and plot
aprs stations.
Tomorrow, I will have access to a set of Garmin Rinos for the
afternoon. I have 22 hours to get this going <grin>.
Is it immediately obvious where my error is? Is there a way to
confirm that the serial port is functional? Is there anything
special about connecting a Rino to the laptop that would increase
the likelihood of the system work? Any other suggestions? One
of the other guys has the other laptop that is running Xastir
( from a binary download running on VMWare). Unfortunately, it
was not compiled with GPSMAN so the Rino options are not available.
Many thanks ............. jt
