Hi all,  
i have rabbit RCM 6700 miniCore. how i can communication via serial port?  
i need send text via serial port, and waiting for reply, and print to stdio.  
In samples i found nothing, only send via port C and receive from port D. In my project i need send and receive in port C.  
Is there sample program? or tutorial?

sorry for my English.

Thanks

Hello,

see the Dynamic C function reference manual, there you can find the APIs to receive and sending data through the com ports.
