IBASIC Controller

Serial I/O from IBASIC Programs

There are two serial ports available for I/O (input / output) to

peripherals external to the Test Set. To bring data in to the Test Set

through the serial port(s) use the IBASIC ENTER command. To send

data out, use the OUTPUT command.

Serial Ports 9 and 10

The Test Set uses a small DB-9 connector on the rear panel for

connecting to the two serial ports. For information about serial port

configuration, refer to the “Test Set Serial Port Configuration” on page

230.

Before using either port, the RS-232 protocol must be established by

setting baud rate, pacing, and the other settings as explained in “Test

Set Serial Port Configuration” on page 230. Functionally, from an I/O

perspective, the two serial ports are identical. However, operationally

there is one major difference. The Serial Port Address 9 settings are

adjustable on the I/O CONFIGURE screen or with IBASIC commands,

while the Serial Port 10 settings are adjustable only with IBASIC

commands. There is no screen for Serial Port 10 settings. For more

information, see the HP-IB Syntax Reference Guide which gives the

command syntax for Serial Port 9 and 10.
