Actually, I was just trying to use the ActiveHome Program as a working tool to see what changes in the CM11a interface took place after programming Macros, House code to monitor, etc.
I was able to program the CM11a with VB6 in NT4 and the NT4 operating system has no problem interfacing with the CM11a on the serial port. I've got it turning lights on and off, dim, bright, and monitoring house codes.
But it appears that the original programmer(s) for ActiveHome ver 1.4x was using a Windows 9x programming environment and out of date Windows API's that didn't support the newer wide format APIs which NT supports, just the Ascii format. That is just a guess. But that appears to be the case. He definitely was not using Windows NT as a programming environment. Which is kind of odd, since most programmers prefer the stability of the NT operating system.
I tried it on Windows 98 and Active Home ver 1.42 works fine. But appreciate the feedback.
