Concatenating Configuration Commands
Commands can be concatenated (added together) in a single string or data block.
Serial Command Status Request
To
ensure that any command was received and accepted, you can send the
Show
Reader Status command:
<?>
.
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-860, 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 an
<H>
command to
restore scanning.
