NOTE:
The GC864 family Wireless Modules (GC864-QUAD and GC864-PY) has two DVI ports
on the system interface.
Only one port can be selected and be active at the time. The choice of DVI port
depends on the needs of the application, but Telit suggests that applications only use
the DVI2 port as this minimizes the impact on the module functionality.
