Ah now I know why you were asking about the first three bytes. Thinking cap screwed on.

Likely were waiting for the SAM testing. Seeing that the SAM interfaces via Rs232 serial (I think) wouldn't it be nice to create a remote connection where the SAM could be interfaced and monitored to our remotely connected systems.

My pgm was fairly robust, but occasionally seemed to miss a few data points.  I guess there was a bus collision and I never bothered to check for valid CRC.  I think the table we've been updating is fully populated for the equipment I have on my system.  I was thinking of making a pgm that will...

I wrote a pgm in C that iterates through every possible address.  You add the start address and end address in the command line parameters. The output is piped to a file of your choosing.  Is this what you were referring too?

Dudes. I'm impressed. Thanks 3tonnes for telling me that things are hopping again. Now I'm inspired.

Hey 3tones, can't seem to e-mail to you either. What I meant by bridge is to connect the bryant software communicating at 9600 to my C pgm communicating with the furnace at 38400. I figure I'll extend my C pgm so that it accepts I/O across a socket, and then do the same with the PC running the...

I believe I was able to decode at 38400, 8,n,1. I've written a small program in C to read ttyS0. Have you also gotten your hands on the Bryant access zone software. Someone posted an old link, I think it's on this board somewhere. It communicates at 9600/8/n/1 but I think I can bridge that...

Nope - but I have added an RS485 board to my bus and am actively receiving the data. I have had some success in seeing a pattern in the communication. It is very much hex based with some Ascii responses. Has anyone been down this path? I can't find much in the way of searching in Google to...
