SPI to MSP430 based board


I am trying to interface Digi board to other MSP430 based board trough SPI, but I am having trouble with SPI.
As I understand there is no dedicated SPI, but Serial port module can be used in SPI mode. When I configure it in SPI mode in kernel I expected to find dev/spi or something like that. Why so??
What about bit banging SPI? Is there some working example or guidelines for Digi??

Than You in advance!

Are you running linux, wince, or netos? I know that there is an SPI driver for both wince/netos. I don’t know about linux.
