Thanks everyone for your help with ReadFile() and WriteFile().
This has speeded up my read/writes several hundred fold.
I now am having some difficulty with timing:

I want to say:
WriteFile(...)      // to tell the peripheral to send me data
while (!readytosend);   // wait until the peripheral is ready
ReadFile(...)                 // read what the peripheral says

Where can I find info on RTS/CTS or DTR/DSP?
I don't see this in the SDK help menu.
Also, I am not sure that the peripheral reads or writes these signals...  I guess I'll find that out if I try to use them.
