I'm working in a project in which I will have to deal with serial communications. For testing, I want make to 2 computers speak to each other (with my interaction) via RS232.
Will the next thing work?
in computer A:
# cat /dev/ttyS0
in computer B:
# echo <something> >> /dev/ttyS0
Will computer A, receive data from B, or not?
If I'm wrong, what would be the easiest way to send something to the other computer?
Ideas are welcome!
