Which function in win32file is throwing the exception ?

It may be that the device only accepts specific baud rates.

>From a quick look at pyserial, it has the buffer sizes hardcoded
to 4096 in the call to win32file.SetupComm.  Another possibility
is that larger buffer sizes are needed for higher baud rates.
