NAME

       Write -- send output to serial port

FUNCTION

       This command causes a stream of characters to be written out
       the serial port. The number of characters is specified in
       io_Length, unless -1 is used, in which case output is sent until
       a null(0x00) is encountered. 
   IO REQUEST
       io_Message      must have mn_ReplyPort initialized
       io_Device       set by OpenDevice
       io_Unit         set by OpenDevice
       io_Command      CMD_WRITE
       io_Flags        Set IOF_QUICK to try quick I/O
       io_Length       number of characters to transmit, or if set
                       to -1 transmit until null encountered in buffer
       io_Data         pointer to block of data to transmit

RESULT

       Error -- if the Write succeded, then io_Error will be null.
           If the Write failed, then the io_Error will be non-zero.
