I have a serial device, which needs to receive the commands ctrl+W and ctrl+V before I can begin programming it. I was trying to use cutecom, but I don't see an option to send control characters.

verbatim, what the instructions say is:

(decimal 23), (decimal 22)

where <> are being used in place of quotes.

  • If there's a button or pulldown for hex input somewhere check that and enter the 0x1716. You mighnt also need 0A0D at the end of it...

The easiest way is to echo -e symbols to /dev/ttyUSB0 or other device.


echo -e "\027\026" > /dev/ttyUSB0

026 and 027 egual decimal 22 and 23.

But your user needs to be in dialout group. Or use sudo.
