Using the com port on the iMX53

Has anyone created an application that opens the com port and listens to incoming messages and sends a response?

 

I'm writing in C and I believe that the "stdio.h" should have everything I need.  When I try to open the port I get error messages.  It doesn't seem to like the parameters:

 

int portnum

 

portnum = open("dev/ttys0", O_RDWR | O_NOCITY | O_NDELAY);
