I am wondering where to find information on programming USB/LPT/Serial ports in the WindowsNT enviroment. I realize that this is much more diffiult than in win95 or Dos because of hardware abstraction.
Under WindowsNT, the serial port exists in the form of COM devices, such as COM1, COM2. To program the serial port, you may use Win32 function calls with C, C++. Or easier solution, ActiveX - MsCOMM with VB. You may also find other 3rd party APIs. Such as Moxa PComm library. You may find it in the web site "www.moxa.com":http://www.moxa.com . It's free and provide file transfer protocol.
