Honeywell 2020-5 User Manual

10 - 3
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 mini-
mum 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.
