3.4.1 WAKE# Signal

WAKE# pin (signal that the module uses to wake up the host) supports software
control.
This signal is used for 3G module to wake up the host. It is designed as an OC gate,
so it should be pulled up by the host and it is active-low.
When the module wakes up the host, the WAKE# pin will output low-level-voltage to
wake the host.
