     Abstract:  When a program wants to utilize a serial port on
                a terminal server for general purpose communication,
                it uses LAT Application Ports.  Before a program
                can use use the application port, it must successfully
                connect the application port to the appropriate
                terminal server port.  The routines in this submission
                provide a simple interface for programs written in C,
                FORTRAN, or almost any VMS programming language
                to manipulate LAT application ports.
                These routines hide the QIO interface provided
                by VMS and provide user friendly procedure calls.
                Some C and FORTRAN examples are included.
