3/16    Does anyone know where to obtain information on PC serial port
        interface, for input AND output? Thanks.
        \_ Pins 2,3 for send/receive.  What more do you need?
           \_ yeah, knowing the port #'s and irq's isn't very
              useful.
                \_ IRQ 3 and 4, 2e8, 3e8, 2f8,3f8.  Anything else?
