Re: [Bacnet-developers] Win32 Port - Timing problems?

[Sam S. <s2l...@s2...>]

Good day Jason,

I believe that there was a discussion on your following statement a few 
months ago:

There is indeed several software packages that can communicate on MS/TP 
on Windows.  Check out BACBeat from www.Polarsoft.com and CAS BACnet 
Explorer from CAS BACnet Explorer.

Effectively, from what I understand, one has to write a kernel mode 
driver to have MS/TP to communicate within Windows.  By doing so, then 
the timing constraints can be met.

Cheers,

Sam
