There's a little known trick that would allow you to get 160 kbps rates
with a PC serial card.  It entails replacing the color crystal on a
standard $10 add-in ISA card to a 5.12 MHz crystal.  Then your 115.2kbps
prescaler will give you a 160 kbps rate.

You will probably have to run in DOS to get this rate, and your cables
will have to be short; about 3 feet.

We used this technique quite effectively as a production line flash loader.

1Mbit/w verify in less than 20 seconds -- 30 seconds with pre-erase.
