I have one simple question:  
Is it possible to communicate with the Q26 extreme via USB Port using Mulitplex Protocol (AT+CMUX)?

Thanking you in anticipation.

I can use M2MStudio, TMT, and TE on the USB port of a Fastrack Supreme (which contains a Q2686).

I beleive that these use CMUX,so I guess it must be possible…
