Given that I just did, and that it cost $55 plus a 1 month delay: if
you want to just ask me, please feel free to do so. That goes for the
whole LAD community.
The relevant pages in the standard (or more precisely, "The Detailed
Specification") state:
page 5:
"Exclusive messages can contain any number of bytes, and can be
terminated either by an End of Exclusive (EOX) or any other Status
byte (except Real Time Messages)."
page 30: lists Real Time Messages:
Timing Clock
Start
Continue
Stop
Active Sensing
System Reset
