JANUS? 2020 Hand-Held Computer (4MB) - Intermec

NF BC Learning About the Software
3
The JANUS Application Simulator lets you run JANUS applications that use
PSK functions on your PC so you can use DOS development tools and
debuggers common in the software industry to debug the applications’ logic
and syntax. (Without the Simulator, you cannot run these applications on a PC
because the PSK functions and interrupts cause a PC to lock up.)
To learn more, see these manuals:
• JANUS PSK for C++ Reference Manual
• JANUS PSK for Basic Reference Manual
• JANUS PSK for Ada Reference Manual
• JANUS Application Simulator User’s Manual
Using IRL and PC-IRL
The JANUS 2020 fully supports IRL, as described in Chapter 7, “Working With
IRL.” You can write, compile, and run IRL programs on your reader. You can
port existing IRL applications to the JANUS platform and take advantage of
special JANUS commands and features.
Intermec recommends you use PC-IRL to create and download IRL programs.
PC-IRL provides IRL programmers with an easy-to-use programming and
debugging environment on a PC.
To learn more, see these manuals:
• IRL Programming Reference Manual
• PC-IRL Reference Manual
Making PSK Applications That Work With BFT
You can create PSK applications that can accept and respond to a host
computer’s request to initiate a binary file transfer (BFT) session.
You need to program your PSK application to accept the Prepare for Reboot
command from any host computer. Your application responds by calling a
Prepare for Reboot procedure (which may consist of housekeeping tasks such
as closing files), and then notifies the PSK library and host computer that the
reader is ready to be rebooted. At that point, the host can reboot the reader and
open a BFT session.
To learn how to create BFT-ready PSK applications, see your JANUS PSK
reference manual. To learn more about BFT, see “Downloading Applications
Across the Network” in Chapter 6.
