 Until then, the primary current focus of the FC Magnetite project is the
 AT-command-controlled modem configuration.  Both TI's original modem fw (TCS211)
 and our recreation thereof in this Magnetite project support not only voice
-calls and SMS, but also CSD, fax and GPRS.  However, before we can really

-assumes the availability of two UARTs: the modem UART presents a classic AT
-command interface which includes the CSD, fax and GPRS functionality, whereas
-the 2nd IrDA UART carries the debug trace channel (RVTMUX) essential for
-developers.  However, only one UART is practically accessible on Mot C139 and
-Pirelli DP-L10 targets; because we could not give up RVTMUX, we gave up the
-classic AT command UART channel instead.  We have implemented a mechanism for
-passing AT commands over RVTMUX, but this mechanism works only for the voice
