As a reference, I've posted my initialisation of the port as
http://pastebin.com/m2b4219aa

When reading/writing, I open the port as:
fd = open(port, O_RDWR )

When writing:
 int flags=TIOCM_RTS;
 ioctl(fd, TIOCMBIS, &flags );
 ret = write(fd, data, sizeof(data));
 usleep(ret*500); // based on the linespeed 19200
 ioctl(fd, TIOCMBIC, &flags );

When reading:
 ret = read(fd, &rxchar, 1);

I hope it gives you any hints on using the port.
