Storage mode
A power management mode on the reader that lets you preserve the life of the
lithium backup battery. Place the reader in Storage mode if you will not use the
reader for 1 week or more. While the reader is in Storage mode, the NiCad
battery pack must be removed; otherwise, the reader slowly drains the battery
pack and backup battery. All data in conventional memory is lost when the
reader enters Storage mode.
Suspend mode
The mode the JANUS reader enters when you press
Suspend mode, the reader saves all memory and turns off the power to most
hardware, including the CPU.
symbology
See bar code symbology.
Text mode
One of two display modes on the reader. By default, the reader uses Text mode
and you can set the display size to 25 x 80, 16 x 20, 8 x 20, 16 x 10, and 8 x 10. If
your application only recognizes DOS mode, you must use a display size of
25 x 80 or 25 x 40. The other display sizes are not DOS standard and are for use
with custom applications. Text mode also supports two character attributes:
blinking and reverse video. Contrast with graphics mode.
timeout
A defined time allowed for an event after which an alternative action is taken.
timeout delay
The time the reader waits between received characters before an I/O
(input/output) error occurs.
TSR program
Terminate and stay resident program. A DOS program that remains loaded in
conventional memory after you have terminated it. You must explicitly unload
the TSR if you want to free the conventional memory it is using.
UART buffer
Universal Asynchronous Receiver/Transmitter buffer. The UART buffer
contains bytes of data being sent or received by the reader. The FIFO control
register controls how the UART buffer operates.
