Concatenating Configuration Commands
Commands can be concatenated (added together) in a single string or data block.
Serial Command Status Request
The status of a specific serial command can be requested by entering the command fol-
lowed by a question mark, for example <K101?>. To see all K commands, send a
<K?> command.
With the MS-3 CCD, each K command is framed with a preamble and postamble and
may be mixed with bar code symbol data. To prevent this, send an <I> command to
disable scanning before sending the K request. Follow the K request with a <H> com-
mand to restore scanning.
Entering Special Characters in Serial Commands
To enter control characters within a serial command, hold down the control key while
typing the desired character.
Entering Special Characters in Embedded Menus

monic characters, such as: <CR><LF><NUL><NUL>.

line feed, press SP, then
