Special Forums UNIX Desktop Questions & Answers cygwin error device or resource busy Post 302354174 by blianna on Thursday 17th of September 2009 10:21:39 AM

Using puTTy it works but my aim was to automate the process.
So I try:

# Open ttyS2 for reading and writing as FD 5
exec 5<>/dev/ttyS2
# Leave this running in the background
cat <&5 &
# Write a command to FD 5
echo "AT" >&5

and I think that it's a good idea!! But now, there is another problem: when I try to send an SMS through At commands I have to communicate the control character [ctrl+z] ^Z to serial port...and I have some troubles to do this.

echo "\032">&5
echo "^Z" >&5

They don't work probably because I had to set up some features with stty but when I try:

stty -F /dev/ttyS2 isig

I face with this error:
stty: /dev/ttyS3: unable to perform all requested operations

Any idea to send control char??
Thank you!!!
