The Teledyne API's implementation of Hessen Protocol allows the user to choose one of
several different modes of response for the analyzer.
This is the Default Setting. Reponses from the instrument are encoded as the traditional
command format. Style and format of responses depend on exact coding of the initiating
command.
Responses from the instrument are always delimited with <STX> (at the beginning of the
response, <ETX> (at the end of the response followed by a 2 digit Block Check Code
(checksum), regardless of the command encoding.
Responses from the instrument are always delimited with <CR> at the beginning and the end of
the string, regardless of the command encoding.
