Well, I trap phone system data from the serial port. I have a start-up script in my rc.local file that pipes the data to a file:
[EMAIL PROTECTED] rc.d]$ cat /usr/bin/osas_logsrxcalls /usr/bin/osas_rotatesrxcalls # Remember, call this script with a background argument '&' cat < /dev/ttySR11 | sh -c 'while read line; do echo "$line" >> /usr/ip/osas/arc hive/SRX_CALLS ; done' The pipe ensures that the SRX_CALLS files is "movable" with the cat process breaking or following the moving inode. My osas_rotatesrxcalls does this: # Rotate captured text file if [ -f /usr/ip/osas/archive/SRX_CALLS ] then /bin/mv /usr/ip/osas/archive/SRX_CALLS_9 /usr/ip/osas/archive/SRX_CALLS_10 /bin/mv /usr/ip/osas/archive/SRX_CALLS_8 /usr/ip/osas/archive/SRX_CALLS_9 /bin/mv /usr/ip/osas/archive/SRX_CALLS_7 /usr/ip/osas/archive/SRX_CALLS_8 /bin/mv /usr/ip/osas/archive/SRX_CALLS_6 /usr/ip/osas/archive/SRX_CALLS_7 /bin/mv /usr/ip/osas/archive/SRX_CALLS_5 /usr/ip/osas/archive/SRX_CALLS_6 /bin/mv /usr/ip/osas/archive/SRX_CALLS_4 /usr/ip/osas/archive/SRX_CALLS_5 /bin/mv /usr/ip/osas/archive/SRX_CALLS_3 /usr/ip/osas/archive/SRX_CALLS_4 /bin/mv /usr/ip/osas/archive/SRX_CALLS_2 /usr/ip/osas/archive/SRX_CALLS_3 /bin/mv /usr/ip/osas/archive/SRX_CALLS_1 /usr/ip/osas/archive/SRX_CALLS_2 /bin/mv /usr/ip/osas/archive/SRX_CALLS /usr/ip/osas/archive/SRX_CALLS_1 fi /bin/cp /usr/ip/osas/archive/SRX_START_1 /usr/ip/osas/archive/SRX_START stty -echo -echoe -echok -echoctl -echoke < /dev/ttySR11 The last stty line just makes sets the serial settings - done a boot time. Linux is good about remebering serial settings. On other unix systems you have to wrap the stty command inside an infinite while loop to make the process hold the tty settings - yuck.
