- Well, the Zoom V.32bis internal has a 16550 on board - Unlike some
- other modems I played with, PCTools System Info reports 16550 on
- a UART search. At $259, I consider it "cheapo" based on price
- (Boca is only $30 less and is, as far as I know, "bottom of the
- barrel" in pricing) - Granted, some of the cheapos don't have it,
- but some do. Moral of the story, look before buying...
