No. Lying to setserial about your baud_base will result in a mysterious change in your serial interface speed. E.g. doubling baud_base will make the UART divide by 2 one extra time, which will half the speed of the port as you didn't really increase the speed of the oscillator. Use stty. But I've never got the -F switch to work. You redirect /dev/ttyS2 to standard input instead: stty options... < /dev/ttyS2 > 2.

(There shouldn't be one unless you put it there.) > 3. What is "modem control" and how do I enable it on a serial port? stty again. The clocal switch decides whether carrier detect is required, for example. crtscts controls hardware handshaking. You need Not Local.
