I have an application program that allows scripting and has a serial port interface for connecting 'lab equipment'. I need to control an LED's brightness. I figured I'd use one the FTDI USB chips and their Virtual Com Port, but I can't figure out what the Virtual Com Port does. The FTDI web site says there is a lot information on the web about using com ports so they are not going to repeat it. Sure I can write to a com port. The data goes to the FTDI chip, goes round and round and goes where and does what? Can anyone here tell me how the FTDI Virtual Com Port works or point me to a web page with information on it?
Thank you
