CHAPTER 5: Controlling the IPSP with PC Commands
5.1 Overview
The Intelligent Printer Switch plus can be controlled by sending software
commands to it from any computer. The ADMENU software automatically
generates the required software commands. This section gives the format
and purpose of each command.
All software commands have the following format:
<PM command {parameters} >
Commands must begin with the three characters <PM and end with the single
character > . In the command templates and examples that appear in this
chapter, upper-case letters are used to represent a key word. Anything in
braces
{ }
is optional. Text in lowercase letters should be replaced by the key
word or option that it represents.
For example, the command to connect to Port 2 would be:
<PM CONNECT 2>
A string of characters will be recognized as a command only if all the
characters are correct, thus making confusion with normal text extremely
unlikely.
Software commands should be sent to the IPSP as a string of ASCII characters.
The best way to do this is to create a file containing the required command
and then just “print” it as needed. There are many other ways to do this,
however, such as inserting the required selection string at the top of a word-
processor document (refer to the user’s manual for your word processor).
Users of IBM compatible computers can even create batch files to send
software commands (see
Section 5.5 ).
Items in a software command can be separated by spaces, tabs, line feeds,
or form feeds; however, only one of these may be used between each item.
