Hand Held Products 2020, 5620 Concatenation of Multiple Commands, Responses, Examples of Query Commands

IMAGETEAM™ 2020/5620 System Manual 10 - 3
Concatenation of Multiple Commands
Multiple commands can be issued within one Prefix/Storage sequence. Only the
Tag, SubTag, and Data fields must be repeated for each command in the
sequence. If additional commands are to be applied to the same Tag, then the
new command sequence is separated with a comma (,) and only the SubTag and
Data fields of the additional command are issued. If the additional command
requires a different Tag field, the command is separated from previous
commands by a semicolon (;).
Responses
The device responds to serial commands with one of three responses:
ACKIndicates a good command which has been processed.
ENQIndicates an invalid Tag or SubTag command.
NAKIndicates the command was good, but the Data field entry was out of the
allowable range for this Tag and SubTag combination, e.g., an entry for a
minimum message length of 100 when the field will only accept 2
characters.
When responding, the device echoes back the command sequence with the
status character inserted directly before each of the punctuation marks (the
period, exclamation point, comma, or semicolon) in the command.
