(fwd) Re: Serial port communication

[Rein Klazes]

Hi,

A bug reported in the users list. Because the reporter prefers just to
work around the problem in his own code, I forward it here.

In short: ReadFile reads a single byte alright from the serial port but
at the same time returns an error GLE = ERROR_INVALID_PARAMETER. With
multiple bytes there are no problems.

There is a code snippet in the attached message.

Rein.
