Hmm. I'd been told that there are a few of the higher end adapters had
true RS232 in them, so should work if you were to have a programmer that
was externally powered. My funds are limited, so I have yet to
experiment with it in hopes it would work. But, now that I think about
it, if my funds weren't limited, I would just buy the "real thing" from
Microchip. My side, then, is inconclusive on this, so I'll have to go
with your thoughts on it for now. ;)
