IV. SAMPLE BASIC LANGUAGE TEST PROGRAM

The BASIC language program below illustrates software sequences

for the NMEA protocol that are displayed on the video monitor.

Also provided are simple routines for inputting the /IN1 thru /

IN4 digital inputs and writing to the /OUT1_BUFFERED output.

The program can be run under DOS using a BASIC interpreter

such as QBASIC by Microsoft Corporation. An interpreter can be

provided at no charge upon request.
