  • Thanks! I had no problem using the screen command in the terminal, but when I try to test it within a simple bash shell, I get an error reporting “Sorry, could not find a PTY”. Here is the script:


    while :
    rfid=screen /dev/cu.usbserial-A600JNHR 9600
    echo “RFID #: $rfid"
    sleep 1
    Any ideas would be great!

No public wish lists :(
