                                 L_LPTSTAT()


Syntax:        L_LPTSTAT(<expN>)


Purpose:       To determine the current status of the specified
               parallel printer interface port.


Arguments:     <expN> is the printer whose status is required and must
               be in the range of 0 and 2.


Returns:       An integer representing the status of the specified
               printer.

               1 = Timed out.
               16 = Printer selected.
               32 = Out of paper.
               64 = Acknowledge.
               128 = Printer not busy.


Usage:         These values could be tested for in the event of a
               printer error using ISPRINTER() and perhaps be used to
               return a meaningful error message.


Examples:      * Determine the status of LPT1
               status = L_LPTSTAT(0)


Language:      Assembler
