Hi,

i'm trying to set the serial port.(XP SP2, Visual Studio 2005). I use
the example code from MSDN "configuring a communications resource".

CreateFile pass through, however GetCommState return 0.With
GetLastError(), i get the error number 87, which means
"ERROR_INVALID_PARAMETER The parameter is incorrect. "
I'm sure the serial port works, because i can use another program to
read/write through it.

thx
Cheng
