I'm trying to echo a command to a serial port that happens to require a "!". In order to send the command I need to escape the ! with a backslash. However, I'm finding that at the other end, the backslash stays there rather than being stripped off, so the received command is also escaped and therefore doesn't work.
Emulated on a terminal: I send jenny@phaedrus:~$ echo "!tts MALE" > /dev/ttyp2 and receive !tts MALE
But I need to receive !tts MALE
Any hints on how to acheive this?
Try single quotes: echo '!tts MALE' > /dev/ttyp2
