        /* todo - possibly remove AFC and do manual CTS */
}

Yes you can but you need to implement this call. Then you can use this code:

/int cmstatus;
//
//ioctl(ttyS, TIOCMGET, &cmstatus);
////cmstatus &= ~TIOCM_RTS;
///cmstatus |= TIOCM_RTS;//
/ioctl(ttyS, TIOCMSET, &cmstatus);

you need to flush the buffer in the middle using tcdrain and wait the the internal serial buffer is empty

unsigned int lsr = 0;

do {
	ioctl(fd, TIOCSERGETLSR, &lsr);
} while (!(lsr & TIOCSER_TEMT));

Or use the RTS/CTS part like gpio pin
