You can use 'ioctl()' with TIOCMGET to get the resiter's status, see http://www.easysw.com/~mike/serial/serial.html#5_1_1 ("Serial Programming Guide for POSIX Operating Systems - Getting the Control Signals")
    #include <unistd.h>
    #include <termios.h>

    int fd;
    int status;

    ioctl(fd, TIOCMGET, &status);
