921600 ?? is that the speed you are trying to communicate serially at?
Is such a serial port speed even possible, or is that a typo?
at any rate, Win32::SerialPort is limited by its Win32API::CommPort
dependency, which I am almost certain has a maximum speed of 128K
I've never seen Win32::SerialPort run at anything faster than 115200.
and I've had some problems with serial modems over 56K
these modules were stablized about six years ago, and I dont think
theyve been updated since. Serial-Port communication is kind of
"trailing-edge" technology these days.
