I have just bought IESM IO+USB expansion card, I have successfully connected my fastrack supreme 10 with PC and send AT commands to my modem. But I have one question is it possible to send commands from microcontroller? on PC i must install drivers that fastrack acts like modem, but what if I want to send data (commands thrue USB) from microcontroller that has USB? or just is it possible to send data to fastrack with no drivers installed on the PC? communication must be done with usb.
I hope someone will understand what I mean, and tell me solution if exists.
