SERIAL

Syntax:                 SERIAL

Use:                    To determine if a serial port exists.

Parameters:             SERIAL

Returns:                The first character in the sending parameter will
                        have a "Y" if a serial port exists, and a "N" if a
                        serial port does not exist.  If you did not pass the
                        parameter correctly (e.g. FOXLIB = "ZERIAL"), your
                        sending parameter will be unchanged.

Example:                . load c:\FOXLIB\serial
                        . FOXLIB = "SERIAL"
                        . call serial with FOXLIB
                        . ?substr(FOXLIB,1,1) = "Y"
                        .T.
                        . rele modu serial

                        From this example, a serial port exists.
