Making More Memory Available On The Reader; Not Installing The Pc Card Drivers - Intermec Janus 2010 User Manual

JANUS 2010 Hand-Held Computer User's Manual
Input Manager Using software interrupts and library functions, your reader
applications can use Input Manager as an interface for all data I/O from the
reader's COM ports, wand, scanner, and keypad. Input Manager also handles
all power management during data I/O. For help with software interrupts and
library functions, see your JANUS PSK reference manual.
You can use Input Manager to customize how the reader handles data from the
keypad, wand, or scanner. The reader can display all input, beep when labels
are scanned, and parse reader commands. For example, when you scan a bar
code label, Input Manager can identify the symbology and if the label includes
reader commands.
Virtual Wedge The Virtual Wedge decodes and manages bar code input,
making the reader functionally equivalent to a wedge reader connected to a
PC. This capacity facilitates rapid porting of PC applications to the reader.
When you scan a bar code label, the Virtual Wedge inserts the data into the
keyboard buffer as if it had been typed. The Virtual Wedge sends configuration
commands to Configuration Manager. The Virtual Wedge also recognizes and
implements reader commands.

Making More Memory Available on the Reader

Your JANUS reader may not have enough conventional memory available for
the applications you want to run. If so, you may be able to free some
conventional memory by performing these tasks:
• Not installing the PC card drivers to free about 60K of memory
• Unloading the Reader Wedge TSR to free about 80K of memory
• Unloading the Configuration Manager TSR to free about 50K of memory

Not Installing the PC Card Drivers

You do not need to install PC card drivers if you are not using PC cards in your
reader. You may be able to save up to 60K in conventional memory by not
installing the drivers.
Note: By default, the SRAM PC card drivers are installed when you boot the reader.
All other drivers are remarked out in the CONFIG.SYS file, which means they are
disabled because they are preceded by the REM characters.
