Hello,

i created a bash-script to send something to serial port
(/dev/ttyACM0) and read the result.

Here my code:

- ---
DEV=/dev/ttyACM0

stty raw -F $DEV ispeed 38400 ospeed 38400 cread -cstopb -echo

echo "@00P0?" > $DEV

while read -r -t 1 LINE
do
	echo $LINE
done < $DEV

echo "Result: $LINE"
- ---

The command will be send out correctly to the serial port. In the
console i can see the correct incoming result (String), but my var
$LINE is empty and doesn`t catch it.

Any clue or hint for me why read does not catch the result?

Thanks for your help,

Michael
