Service Request
(SRQ)
The 1256 may generate a service request (SRQ) in response to a
variety of events. These events include detecting a programming
error or confidence mode failure, generating a response to a query,
and many others.
Consult the
IEEE-488.2 Status Description

Chapter 5,
SCPI Command BASICS
for a description of how to program the
1256 to generate a service request.
Using the RS-232
Interface
Basic RS-232
Information
The RS-232 interface provides a simple way to control the 1256
from virtually any computer. Nearly every computer has a serial
(Com) port. The only extra hardware required is a serial cable.
This section gives information about connecting the 1256 to the
computer via serial cable, setting up the 1256 for serial port
operation, and communicating with the 1256 by using a terminal
emulation program.
