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 SeeAlso: AH=01h,AH=02h,AH=84h"COMM-DRV",AH=85h"COMM-DRV",AH=8Eh"COMM-DRV"
