welllllll, back in the days before hacked drivers that would
wiggle the break bit in the DH-11 registers, we did the following,
assuming the port was set for some relatively speedy speed (4800 or 9600):

	(1) set the port to the slowest baud rate it supports - probably 50 baud
	(2) set the mode for 8 bits no parity
	(3) write a buffer of 0x00 to the port

usually worked just fine
