Fastrack Extreme simultaneous data and AT command access


#1

Does the Fastrack Extreme give you 1 or 2 virtual serial ports on the USB interface?
Many USB only 3G modems give you 2 virtual serial ports via USB and this is nice because you then don’t need to use multiplexing mode (AT+CMUX) to send SMS when you have an active data connection. You can use 1 serial port for you data connection PPP and the other for AT commands.
I can’t find any detail on this sort of thing in the Wavecom manuals and I don’t have one to plug in and see.
