The applications you run on your reader control how it operates, interacts with<br />

• Ada<br />

• Borland C/C++<br />

• Clipper<br />

• IRL<br />

• Microsoft C/C++<br />

• Microsoft QuickBasic<br />

<strong>Intermec</strong> also offers these products that help you create applications for your<br />

Using <strong>JANUS</strong> PSK and <strong>JANUS</strong> Application Simulator<br />

The <strong>JANUS</strong> <strong>2020</strong> fully supports the <strong>JANUS</strong> Programmer’s Software Kit (PSK).<br />

Although many applications can be written with standard language functions,<br />

you can create applications using C or Basic that incorporate PSK library<br />

functions and <strong>Intermec</strong>-specific system software interrupts. These functions<br />

and interrupts give the programmer low-level control over the reader’s<br />

hardware, such as the backlight, viewport, communications using <strong>Intermec</strong><br />

protocols, and power management statistics.
