Lpc2000

Uart1 supports many modem control signals, but I only need TXD and 
RXD.  

I understand from the archives that SPI will not work unless all 
(four) of its signals are actually enabled on physical I/O pins.  I'm 
hoping this is not also true for uart1, which would waste many pins.  

Is it possible (on the LPC2106) to enable uart1 but not enable all 
the signals to be connected to external I/O pins?
