I could help, but my time/effort cost more than FREE...

However, if you attempt to convert this over to PBP yourself, and you have problems, I am absolutely sure that a number of people here on these forums would be more than happy to assist in the endeavour.

so u will help me to do that or ????

I think skimask's point is the folks on this forum will help answer specific questions but can't do the work for you.

If you want the work done for you some member are willing to do it but they will charge for their services.

and how much that will cost

I don't think you'll find anyone to convert that program.
It's the absolute worst ASM program I've ever seen.

No comments, numbered labels, yuck!

I doubt that it could be converted without extensive knowlege of the protocol.
And if they already knew the protocol, it would be easier to just rewrite it from scratch.

thanks for your trying there are another ones do not want to help at all ???

Here is what you do.

Forget about the assembly, most likely will not work for you.
From the zip you provided.

I have tested this only with 1227747 ECM but it should work also with other 160 baud units after you have verified / altered ALDL data stream decoding to match with your application.

You can blink an LED and make a LCD work. Learn about serial communications and write you own code. Then you can say that PBP paid for its self.

Seems like the trick is in finding the protocol.
