IBASIC Controller
Method #2. Developing Programs on the Test Set Using the IBASIC EDIT Mode
Method #2. Developing Programs on the Test
Set Using the IBASIC EDIT Mode
If a BASIC language computer is not available, program development
can be done directly on the Test Set using the IBASIC EDIT mode. A
terminal or PC connected to the Test Set through RS-232 is used as the
CRT and keyboard for the Test Set’s built-in IBASIC controller. In this
method, the program always resides in the Test Set and can be run at
any time. Mass storage is usually a PC card. When running IBASIC
programs on the Test Set’s internal controller, the Test Set displays only
the IBASIC screen.
The Test Set’s IBASIC controller has an editor that is interactive with a
terminal or PC over the RS-232 serial port. (The editor does not work
unless a terminal or PC with terminal emulator is connected to Serial
Port 9.) The editor, hereafter referred to as the “IBASIC EDIT Mode”,
allows the programmer to develop code directly in the Test Set with no
uploading or downloading. The IBASIC EDIT Mode can be used to
develop programs from scratch or to modify existing programs. Refer to
“Interfacing to the IBASIC Controller using Serial Ports” on page 230
for information on connecting a terminal or PC to the Test Set.
Selecting the IBASIC Command Line Field
To use the IBASIC EDIT Mode for program development, the IBASIC
Command Line field must be displayed on the Test Set and Serial Port 9
must be connected to the IBASIC Command Line field. An IBASIC
command, sent as a series of ASCII characters through Serial Port 9,
will appear on the IBASIC Command Line field. When a carriage
return/line feed is encountered, the Test Set will attempt to execute the
command. To display the IBASIC Command Line field on the Test Set
execute the following steps:
1. Press the TESTS key.
2. The SOFTWARE MENU screen will be displayed.
3. Using the rotary knob, position the cursor on the IBASIC Cntrl field
and select it.
4. The TESTS (IBASIC Controller) screen will be displayed.
5. The small horizontal rectangle at the top-left is the IBASIC Command
Line.
