We engaged the same problem some days ago! We are working on a Msp430
architecture, but I suppose that your problem is quite similar, even if you
haven't specified your architecture...

However, as you can see here[1], the SerialActiveMessageC is based on the
SerialDispatcherC component[2], that's based on PlatformSerialC[3].

The latter is based on Msp430Uart1C, that provides access to the Uart1
through UartByte and UartStream interfaces. By replacing it witm Msp430Uart0C
you can choose the Uart component.

Be careful: I've found out that the reference manual isn't complete! You
may need to check your installation directory tree!
