-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 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 -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.22 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBCgAGBQJTccOgAAoJEFF6fE6T32A8cgUH/3UHMLwzaG7tdaCM6otzFt/b TiVraCsAUMChnBjHpSRg8qphk01NHb+u0QXjFO74WQgznylyFDW68sO5drk90sOl jYy8tFkUn06JkVMuZbyfyGtrQA2kx5zz9sUBN07w9Gl+BzWL+h0Pp3hxfV7URzZF thzSMLJ5OEogZhbCsIixnC+TzTBZtDAVIMpyRxzEHoM/qwt+g3JAzIJPVi6MiUGs FxyDLU+gSI3AnKgiKQLoSP2cqK1/YBwczzsOjeQcW/1vcAiz45qImSyhj+uZujoK 3V4WAoxT5NNS0zdlzs1wO0+9mRcxd09JnsmPxcM9fjIPUPrVb/Z1RNF4GOUQ28M= =pm9c -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
