is it really possible?
im using the `cat` command to listen to the port..while im listening, that command is active in the background..something like:
cat < /dev/ttyS0 > temp
so while this crook is listening to the port, if i try to send a command through the port like this:
echo $command > /dev/ttyS0
the echo command hangs, since that port is already locked by `cat ...`
in case u think of asking, al this `tamasha` (drama) has to be done using one serial port only..cant use any other port xcept /dev/ttyS0
