Controller Commands
Commands and responses are in the form of ASCII character
strings terminated with a carriage return <CR> ASCII character
13 (hex).
If the state variable LINEFEED MODE = ON, a linefeed charac-
ter (<LF>, 0Ah, 10d) will follow the carriage return.
Incoming messages (to the MB1000) shall be terminated with
one of the following characters: NUL (00h, 00d),
carriage return (<CR>, 0Dh, 13d) or line feed (<LF>, 0Ah, 10d).
The MB1000 shall discard the incoming message under the fol-
lowing conditions:
The message overruns the receiver buffer (32 characters).
No terminating character (NUL, <CR>, <LF>) is received within
500ms of receipt of the last character.
