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
