programming language. You can program the BASIC module using an
ASCII terminal or a personal computer running ASCII terminal emulation

1747-PBASE).
Refer to Chapter 2 for additional information on port configuration.
ASCII Terminal Interface
Use an ASCII terminal to enter a BASIC program one line at a time to
your BASIC module through port PRT1. The ASCII terminal connected to
the BASIC module must be an industrial terminal, workstation, or personal
computer (without the BASIC development software) that communicates
in alphanumeric mode. An ASCII terminal can also be used to display
charts or graphs generated by your BASIC program.
