That's pretty much what I thought was the situation.

I'm using 18F parts and my programer takes advantages of the paged write
modes so I don't think I can make that go any faster, and the RS-232
link is maxed out as well.

BTW, thanks for answering my question, not some question you thought I
should have asked ;-)
