DATA is the data returned and is always a series of 2 byte integers. If 4 words were requested then
DBC would be 8 and there would be 8 data bytes or 4 data words containing the requested data.
The format of the data is 4800,N,8,1 meaning 4800 baud, no parity, and 1 stop bit.
Below is a table of currently available messages provided by the MicroM programmers, followed by
a description where necessary.
Messages 00, 05, 08, 10, 15, 21 and 26 are unique in that a limited number of successive registers can
be combined with these requests. For example, a request to message 00 can contain up to 6 data
words. The response to this would contain STATUS, MSGN, GSTAT, TIMER, FLAME and
LOGSTAT. If the requested data word count (DAT) were to be 2 then the response would contain
