I always thought of this backchannel as a debugging breakpoint which causes an JTAG data transfer from or to an MSP stub function when the function is called and the breakpoint is hit. Nobody ever told how it really works, only that it is no real UART (neither hardware nor software) on the launchpad side. It is mainly used to provide a console while inside a debugging session of the IAR debugger.
Well, I might be totally wrong, but that's what I extracted from all the discussion on e2e. And all these discussions ended with this backchannel not being easily (or not at all) usable for own stand-alone projects, even under windows.

When I plug it in under windows several devices are created, one of them is the uart back-channel, from which I can read out the output of the temperature demo. How can this be done under linux? I have studied the mspdebug man page, but found no hint...
