Hi

Good news! I tested all 5 codes posted by galileo01 and all of them work perfectly!
All I need now is the .irp file that generated those codes and I can generate and test the whole set.

I will make an irp out of the lines posted by John and run it through makehex to try that this evening.

For background info, I used IRTool with DecodeIR.DLL to decode signals from my remote and it returns...
Protocol : Teac-K
Device : 0.4
OBC: 0
EFC: 181

To test the signals I have given up on the old pocket pc. I am using IR receiver and blaster thats comes with the Windows Media Centre remote plus the freeware 'IR Server Suite' software.

Thank you all for your help so far
Bill
