Introduction To The Janus Application Simulator - Intermec Janus 2010 User Manual

This chapter introduces the JANUS Application Simulator, explains how to install
the software, and describes how to make your PC mimic a JANUS reader.

Introduction to the JANUS Application Simulator

Applications created for JANUS readers may contain JANUS PSK library
functions and JANUS-specific system interrupts that—when run on a PC
instead of a reader—cause a PC to lock up.
With the JANUS Application Simulator, however, you can run JANUS
applications on a PC. The Simulator captures those functions and interrupts
before they can disrupt the PC. The Simulator then uses those functions and
interrupts to make the PC mimic a JANUS reader, allowing you to run and
debug any JANUS application on your PC.
The JANUS Application Simulator operates as shown in this illustration.
Briefly, while a JANUS
application is processing on
a PC, it may issue a JANUS-
specific system interrupt.
The Simulator TSR captures
the interrupt, uses values
from the INI file to
assemble a response, and
then sends the response to
the JANUS application.
The JANUS application
acccepts the response and
continues processing.
For a detailed technical
description, see "How the
JANUS Application
Simulator Works" later in
this chapter.
