How can I use COM 10 and higher ports?
A special prefix is needed (it's Windows feature):
// Delphi
ComPort.DeviceName := '\\.\COM10';

// C++ Builder
ComPort->DeviceName = "\\\\.\\COM10";
Link error: "Unable to open COMPORT.OBJ" in C++ Builder.
Add comportp.lib file to your project using Project Manager or using #pragma link directive:
