Write -- send output to parallel port
This command causes a stream of characters to be written to the
parallel output register. The number of characters is specified in
io_Length, unless -1 is used, in which case output is sent until
a zero byte occurs in the data. This is independent of, and may be
used simultaneously with setting the EOFMODE in io_ParFlags and using
the PTermArray to terminate the read or write.
IO REQUEST
io_Message mn_ReplyPort initialized
io_Device set by OpenDevice
io_Unit set by OpenDevice
io_Command CMD_WRITE (03)
io_Flags If IOF_QUICK is set, driver will attempt Quick IO
io_Length number of characters to transmit, or if set
to -1 send until zero byte encountered
io_Data pointer to block of data to transmit
io_Error -- If the Write succeded, then io_Error will be null.
If the Write failed, then io_Error will contain an error code.
