IBASIC Controller

Interfacing to the IBASIC Controller using Serial Ports

PC Configuration

To prepare for IBASIC program development, the external PC or

terminal must be configured to operate with the Test Set. This

configuration includes

• Hardware

• Terminal Emulator Software

PC Serial Port Configuration

Connect the Test Set’s Serial Port 9 to a serial I/O (input/output) port on

the PC. On many PCs, a serial port is available as either a 25-pin DB-25

(female) connector or a 9-pin DB-9 (male) connector. This port can be

configured as COM1, COM2, COM3, or COM4 (communications port 1,

2, 3, or 4) depending on the installed PC hardware and user-defined

setup. Refer to the instructions shipped with the PC for hardware and

software configuration information.

Terminal Emulator Configuration Information

A “terminal emulator” is an application program running on the PC

that communicates with one of the serial communication ports installed

in the PC. It provides a bi-directional means of sending and receiving

ASCII characters to the Test Set’s serial port.

In general, a “terminal emulator” enables the PC to act like a dedicated

computer terminal. This type of terminal was used before PCs to allow

remote users to communicate through RS232 with central mainframe

computers. An ANSI-compatible terminal like the Digital Equipment

Corporation VT-100 can be used to directly communicate with the Test

Set. PC terminal emulation application programs have been designed to

have setup fields much like these older technology terminals.
