Well, it seems like RS-232 is (almost) dead... long live to USB.
I must admit I didn't suppose that the programmer interface was called to become a major issue... it has happened though, so let's go face it.
Bill, I'm really sorry to know of your troubles, I thought you had managed to (re)-pogram your modules since you didn't mention further problems after I sent your Clonix back.
Chris is more than probably right, RS-232 shouldn't be being used (in that programmer) as a "real" serial inteface, but as a simple "signals & timing generator" controlled by the software. Thus the USB<>RS-232 adapter more likely won't work at all.
Fortunatelly, other chances are... , unfortunatelly (as usual), some more expensive ones. Namely, "real" USB programmer (some $30 - $40); and Parallel port Programmer, just about the same price.
Drawbacks (appart from the price itself):
- They both need an external power supply to operate. Mostly any wall-wart over 12v - 15v DC fits the task.
- IC-Prog does not seem to support USB programmers. This is not a big deal really, since every programmer has its own software and .HEX files, generated during the configuration process, are standard and fully interchangeable.
Anyhow I'm now testing with an external supply for the programming voltage (the "real" problem with laptops) and will inform you along the next week.
