Not yet, because almost all GSM/UMTS modems that I've seen provide 2 or more AT-capable serial ports and thus we don't require GSM MUX-ing support yet. However, there may be some more embedded devices that only provide one serial port and do require MUX-ing. I've never seen a CDMA/EVDO device that implements AT+CMUX. Alan Cox posted patches a while ago to push the MUX layer down into the kernel, but there are also implementations of it that we could use in ModemManager. There just hasn't been a great need to do so yet. Also, some modems simply lie about their CMUX support which complicates things.
