IM_WEDGE

Wedge mode

IM_PROGRAMMER

IM_DESKTOP

Desktop mode

Notes:

There are three different reader input modes: Wedge, Programmer, and

Desktop. These different modes affect how the reader interprets and stores

input.

Wedge Mode   Keypad and label input goes into the keyboard buffer with

minimal filtering. Wedge mode is the default mode at the DOS prompt after

reader services (RSERVICE.EXE) is loaded. Use Wedge mode when the

reader is running an application that uses the Virtual Wedge. When in this

mode, use standard input functions, such as TEXT_IO.Get, to retrieve

keypad or label input.

Wedge mode does not take full advantage of the reader’s power

management capabilities. You will probably notice reduced battery life

when the reader is in this mode compared to either Programmer or Desktop

mode. For more information on power management, see Chapter 5,

“Advanced Programming,” in the PSK Reference Manual.

Programmer Mode   Inputs are echoed to the screen. Reader commands are

executed and saved. Use Programmer mode when the reader is executing

IRL commands. In general, when you are running an application that uses

the function libraries or software interrupts, the reader should be in

Programmer mode.
