INT 14 - COURIERS.COM - START OUTPUT                                            
	AH = 86h
	ES:BX -> output buffer

Return: nothing

INT 14 - COMM-DRV v14.0 - SET INPUT/OUTPUT TIMEOUTS                             
	AH = 86h
	BL = maximum clock ticks to wait before signalling error on input func
	BH = maximum clock ticks to wait before signalling error on output
	DX = port number
	SI = input timeout in clock ticks if BL=FFh and BH=FFh
	DI = output timeout in clock ticks if BL=FFh and BH=FFh
Return: AH bit 7 set on error
	AH bit 7 clear if successful
Note:	functions 02h, 85h, and 8Eh will wait for the input timeout before
	  returning an error when no data is available; functions 01h and 84h
	  will wait for the output timeout before returning an error if there
	  is no space to output the data
