Defining the Reader Commands

Chapter 11, "Reader Command Reference," describes all the reader commands
that you can enable or disable with Command Processing, except Alternate
Key Code Entry and Multiple-Read Labels. These two reader commands are
described next.

Alternate Key Code Entry

If you enable the Alternate Key Code Entry command, you can use each key's
four-digit hexadecimal key code value in bar code labels to select options, enter
data, and move around in IC.EXE, Communications Manager, and the IRL
Desktop. For example, you can scan this label to move the cursor to the right in
IC.EXE:
Cursor Right
*..4DE0*
*..4DE0*
If you disable the Alternate Key Code Entry command, the reader will interpret
the hexadecimal key code value as regular data rather than as a code for a
specific key or action. For help, see "Scanning Bar Codes to Select Menu
Options" in Appendix C.

Multiple-Read Labels

A bar code label that has a space as the first character after the start code is a
multiple-read label. The reader stores a multiple-read label in the buffer until
you execute a command to transmit the label or scan a regular label. A regular
bar code label is executed as soon as you scan it. If you use Command
Processing, IC.EXE, or another method to disable multiple-read labels, the
reader processes the bar code label as a regular label and reads and decodes the
space as data.
Syntax: <Start Code><SP>data<Stop Code>
