on the development board is there the standard RS232 driver - - - it inverts.

on your board did you directly connect the pin to the connector if so - - - check the settings for the SCI,  and have the transmitter inverted - - - might need to do the same with the receiver setting.

I direct connect and invert both of these settings. - - - -  Development board allows for providing and handling full RS232 levels.
