Using Reader Services

Reader Services are programs that decode bar codes, process data input and
output (I/O), configure the reader, and handle all power management for the
reader. AUTOEXEC.BAT loads Reader Services when you boot the reader. You
do not interact directly with Reader Services because they operate as part of the
reader's system software. You can create applications that use Reader Services.
For help, see your JANUS PSK reference manual.
Reader Services include these programs:
Communications Utilities Communications Utilities are transmit and receive
functions that you can call with PSK functions or software interrupts.
Communications Utilities let the reader transmit and receive buffers or bytes of
data regardless of the communications protocol that you use.
Configuration Manager Configuration Manager maintains the reader's current
configuration file (such as JANUS.INI), ensures that the reader operates
according to that configuration, and lets you change the reader's configuration
file. Configuration Manager is a terminate and stay resident program (TSR)
that loads into the reader's memory during a warm or cold boot. For help, see
"Unloading and Loading Configuration Manager TSR" later in this chapter.
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.
