I need to add a step to my release checklist to keep the
docs/website/code in sync.

Your guess is correct. I only checkbox the service on the website if
we have a demo of that service.

The encoding and decoding is probably correct - but creating a demo
would help to verify that.

SubscribeCOV handling would need to be added to demo/server to allow
subscriptions to properties.

A SubscribeCOV client demo application would need to be created to
send SubscribeCOV requests.

ReadPropertyMultiple is already added to demo/server that integrates
into the demo objects.  I tested the server using VTS3 and monitored
with WireShark.  There are actually some fixes for RPM in subversion -
hope to release them soon.

A ReadPropertyMultiple client demo application would need to be
created to send ReadPropertyMultiple requests.

You are welcome to contribute to creating a command line demo.  I
would suggest that you start with the latest code from subversion
since I moved the source and header files to their own directories.
The demos now rely on a BACnet library from the lib directory which
makes maintaining the demos a lot easier.

Best Regards,

Steve
