    stty and serial ports


    I'm trying to find the right set of stty parameter settings such that I can send the string "TEST \r" to the device hooked up on my serial port. I'm using the following command: echo "TEST \r" > /dev/xxx. I'm having difficulties managing all the permutations of mapping new line characters to carriage returns and vice versa and in the end it doesn't seem like I'm having success sending the actual CR to the device. Could someone help?

    Try using the "-e" flag to echo, e.g.:
    [user@host]$ echo -e "\r\n" > foo
    [user@host]$ cat -v foo

    yes, that was it, thank you.
