Hi, if you are a beginner in .NET or in one of its languages, then a serial port application is not a good start. You should get well acquainted with the platform before you start tackling a serial communication, since that is, although not very complex, well hard to debug and get it right, since it takes some doing to figure out which end is or isn't doing what. Once you know .NET and either C# or VB.NET you will need the SerialPort class. There are some good articles on CodeProject about serial communication. The port being USB connected is rather irrelevant, assuming you install the driver that came with the USB-to-serial cable. The driver turns the port into a regular serial port, so it shows up in all serial port enumerations, and most/all serial apps can use it, whether HyperTerminal or some .NET based app using SerialPort class. The app never is aware the USB-based serial port is connected in a different manner, all the nasty details are hidden by Windows and the device drivers. :)
