if you are working on a radio controlled car why not talk to it directly using WiFi ? all modern laptops are equiped with WiFi. The car could be equipend with a microcontroller with a WiFi interface and you could write a VB program to send TCP or UDP packets to the car. Are you also going to write the code for the car or is someone else doing that?
