Sometimes we require to communicate with an external device like a printer, microcontroller board or any serial device using the serial port of a windows machine. There is a lot of serial application available like Hercules, HyperTerminal, Docklight, ..etc. We can use any one of them for serial communication but sometimes we require to create our

I have worked on the windows printer driver, where I have to install the port monitor silently without user interaction. It is a user-mode DLL which responsible for providing a communications path between the user-mode print spooler and the kernel-mode port drivers that access I/O port hardware. You can also check the below article, How
