Tony,

The script will depend on your particular setup. In our environment 
(using Vyacheslav Frolov's t38modem), the following script resets a 
failed instance of t38modem when it is detected as 'wedged' by HylaFAX:

[root@hylafax]# cat resetmodem
#!/bin/bash
# this is ran from the 'wedged' script, with the $device parameter 
'/dev/ttyx0' for example
DEV="`basename $1`"
#echo "Device is ${DEV}"
PID="`ps -C t38modem -o pid,cmd | grep ${DEV} | grep -v grep| awk 
'{print $1}'`"
#echo "PID is ${PID}"
# try a nice kill first
kill ${PID} >/dev/null 2>&1
sleep 10
# enough playing - kill for real now
kill -9 ${PID} >/dev/null 2>&1
exit

As you can see, the above simply tries to kill the rogue t38modem 
process, however, we run t38modem instances from inside /etc/inittab, 
which ensures they are re-started properly after such an abrupt kill.

[root@hylafax]# ps -C t38modem -o pid,cmd
 PID CMD
23558 /usr/local/bin/t38modem -p ttyya
3610 /usr/local/bin/t38modem -p ttyy0
10969 /usr/local/bin/t38modem -p ttyyb
8545 /usr/local/bin/t38modem -p ttyxb
29360 /usr/local/bin/t38modem -p ttyx7

hope the above is useful, cheers,
Jordan Kojouharov
