The "Monitor" mode is used to control the IJL/3 without any programming. It is useful for evaluating the product, debugging the host to IJL/3 interface or simply setting up a quick document labeling project without requiring any programming.
To control the IJL/3 with Monitor mode, simply attach a terminal or use a terminal emulator on your computer. Press the space bar three times and the IJL/3 will enter Monitor mode. All of the Monitor commands are single character, sometimes followed by a space and parameters, and terminated by the "return" key (the ASCII newline character). Commands are prompted for with a '>' character and responded to with an 'OK'. A list of the commands can be displayed by typing "?" followed by the "return" key.
The Developer's Guide includes a specification of all the Normal and Monitor mode commands and the computer communications port.
