I note that the pins (PD4 and PD5) for Serial Port B for the RCM3700
are listed as Alternate Serial Port B. Is there additional code that
I have to include in my defines to enable port B for serial
communication? I currently have it connected to an RS232 level
shifter but have been unable to communicate with this port.

Add the following define to use the port D pins:
#define SERB_USEPORTD

We have noticed that on the new RCM3700 target,
it is now necessary to set the data direction register
when using port B, whereas with the older boards this was not
required.
