uartfax.c: pull from Tourmaline (GTM900 RI output) In addition to the primary intent of bringing in GTM900 RI output support, pulling uartfax.c wholesale from Tourmaline also changes the initial_time argument in the two NU_Create_Timer() calls from 0 to 1. This change is required for the new version of Nucleus used in Tourmaline and Selenite (and apparently also used by TI in LoCosto), and it is harmless (no effect) for the original TCS211 version of Nucleus used in Magnetite. The new philosophical model being adopted is that Tourmaline is our new development head firmware, whereas Magnetite will now be maintained similarly to how Linux maintainers treat stable kernels: changes will be backported from Tourmaline if they are deemed appropriate for stable modem firmware.
