Re: Help serial port communication

["Jens B. Jorgensen" <jjorgens@bdsinc.com>]

Here's some code you can build on:

        struct termios  ti;
        int             modem;

        modem = open("/dev/ttyS1", O_RDWR, 0);
        ioctl(modem, TCGETS, &ti); /* fill the termios struct with the
current settings */
        cfsetispeed(&ti, B9600); /* set input speed to 9600, could be B300 -
B230400 */
        cfsetospeed(&ti, B9600); /* set output speed */
        ioctl(modem, TCSETS, &ti);
        close(modem);

You can check out the termios man page for more details.
