* Sagetech protocol for host message building and parsing.
*
* This module performs both the following:
* 1. Parses raw Sagetech host messages defined in the SDIM and
* returns a populated struct dataset of the message type.
* 2. Receives a populated struct dataset of the desired host message
* and returns the corresponding raw message data buffer.
