MODMRLS

Syntax:                 MODMRLS

Use:                    To determine the status of receive line signal
                        detect.

Parameters:             COM0 for com1, COM1 for com2, COM2 for com3, and
                        COM3 for com4.

Returns:                The first character in the sending parameter will
                        have a "Y" if receive line signal detect is turned
                        on, a "N" if receive line signal detect is turned
                        off. If you did not pass the parameter correctly
                        (e.g. FOXLIB = "ZOM0"), your sending parameter
                        will be unchanged.

Example:                . load c:\FOXLIB\modmrls
                        . FOXLIB = "COM0"
                        . call modmrls with FOXLIB
                        . ?substr(FOXLIB,1,1) = "Y"
                        .T.
                        . rele modu modmrls

                        From this example, receive line signal detect is
                        turned on.
