abyrvalgThanks again for your replies and input.
Sorry for the lack of feedback from me, my wife and her friend have just brought 2nd hand cars, and with me being an ex grease monkey I have been roped into doing full service on there cars, and fixing any other problems.
I would not have any idea where to even think about starting with regards to decoding the software it's self.
The Mirac control software can be downloaded direct for the Denford where site here:
http://www.denfordata.com/downloads/dos/MIRAC.zipI am looking to try and get back into my workshop this weekend to start probing more data from the serial lines.
Can anyone here recommend a program for MS-DOS so that I can send the serial commands back to the control board for testing?
Yes I could use the windows computer that I am using for sniffing the serial data, but I can't inject data back into the serial with the lathe computer still connected, and moving a 1m x 1m x 0.6m, 350Kg lathe about in a small working is not an easy task.
