Driver for the Apple&nbsp;IIgs serial ports (printer and modem).

Note that transmits are not interrupt driven, and the transceiver blocks if

The driver defaults to opening the modem port. Calling <tt/ser_apple2_slot()/
prior to <tt/ser_open()/ allows to select the printer port (1) or the modem
port (0).
