Quoting Sergey Vlasov <vsu@xxxxxxxxxxx>:
TIOCMBIS with zero argument won't do anything. If you need to lower DTR and RTS, you need to call TIOCMBIC instead: int mask = TIOCM_DTR | TIOCM_RTS; ioctl(tty_fd, TIOCMBIC, &mask);
Thankyou Rob and Sergey, that makes perfect sense once you realise what the 'S' and 'C' in TIOCMBIS/TIOCMBIC mean. :) My application code is now working in an unpatched 2.6.38 kernel.
