12.2 Configuration of the UART2
The Development Kit Q26 acts as a DCE and is connected to a DTE (PC or terminal)
with a "straight cable".
There are only 4 signals on the UART2.
12.3 Enable UART2 ("EN2/GPIO1")
A switch "EN2/GPIO1" may enable the shutdown mode of the RS232 transceiver.
By default, the RS232 transceiver is in active mode (switch to "EN2").
For other cases, Wavecom software allows customer to enable the shutdown mode
by using the GPIO1.
