writing to serial port with a shell script

Question

I need to communicate with a serial device by sending it ascii characters. I know that in Linux you can use fopen() to write to a serial port, but I didn't know if you could do that from a shell. If not, is there another simple way to do this?

Answer 1

I believe you can simply redirect/cat data to the serial port from the shell. You'll want to use setserial(8) to configure baud and other information first.
