7.3
UART1
UART1 is connected to D-SUB connector (CN6) via RS-232C driver and JP.
Communication between i.MX31 and RS-232C driver is defined as DCE (MODEM).
Switchover between straight and cross connections can be achieved through JP setting. This is used for console
output of Linux.

UART2
UART2 shares the same lines of D-SUB connector (CN5) and CN7 lines. Appropriate setting of the switch enables
the RS-232C driver connected to D-SUB connector (CN5) for use.
Communication between i.MX31 and RS-232C driver is defined as DTE (COM).
