AT command interface works!
The cause of the breakage was the same Nucleus API issue with NU_Create_Timer()
which we encountered at the very beginning of this project with Riviera timers:
the code in uartfax.c from TCS211 was passing 0 as the initial dummy value for
the timer duration, and our FreeNucleus version doesn't like it. The fix is
the same: pass 1 as the initial dummy value instead.
