Responses
The device responds to serial commands with one of three responses:
ACK
Indicates a good command which has been processed.
ENQ
Indicates an invalid Tag or SubTag command. 
NAK
Indicates 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.
