Is there a way that I could possibly have the script monitor /proc/tty/driver/serial I guess I should be asking if there is a way to connect two pins through the button hooked up to the serial port that would change the values in /proc/tty/driver/serial so that I could monitor that file and if a change occured, it would fire off a script to start recording, and then when the button is released it would change /proc/tty/driver/serial back to normal and stop recording?
This is the closest I've come so far to finding any answers via the almighty google. ------------------- #/bin/bash while true do read LINE < /dev/tty0S echo $LINE done ------------------- http://www.easysw.com/~mike/serial/index.html ------------------- http://www.linuxselfhelp.com/HOWTO/Serial-HOWTO.html ------------------- On 7/6/05, -ray <[EMAIL PROTECTED]> wrote: > > It can definitely be done.
