Greetings from the BACnet committee and working group meetings in New York City!

Please refer to the comment included at the top of each source and
header file for license and copyright information.  Only a subset of
files are licensed under the GPL (with exception).

The GPL with exception for embedding are the same as from the eCos
project, and there are details about the interpretation here:
<http://ecos.sourceware.org/license-overview.html>

>From that site, "In the simplest terms, when you distribute anything
containing [the GPL licensed BACnet Stack at SourceForge] code, you
must make the source code to [BACnet Stack at SourceForge] available
under the terms of the GPL."  "You do not have to distribute any code
under the terms of the GPL other than [BACnet Stack at SourceForge]
code or code derived from [the GPL licensed BACnet Stack at
SourceForge code]."

It is sufficient to document that your product uses the BACnet Stack
at Sourceforge by a simple weblink to <http://bacnet.sourceforge.net/>
along with an offer to provide the BACnet Stack at Sourceforge source
code to the users of the product.  Or we can just add a link about
your product to the <http://bacnet.sourceforge.net/> website.

> 2. Where and how I can get 'vendor_id'?

A free vendor ID is available from ASHRAE Manager of Standards.
Details about how to do that are on this ASHRAE website page under
BACnet Vendor ID Numbers:

> 3. Which version  have Alarm/Event functions? I use 0.4.1.

The BACnet Stack at SourceForge does not have Alarm/Event functions
implemented at this time. Sorry!

I assume that you refer to BTL Mark and BACnet Testing Labs from
BACnet International.  There is information on their website:
