Setup tris when using rs232

Is it necessary to setup the tris of port c when using normal rs232 between 2 pics.
I am trying to communicate with another pic using rs232 but i can't get the coms going. I am using some of the other outputs of pin c for RF sending using a cc1000.
In the program they use fast io but to i need to insert that also in the receive side or can i just use the normal interrupt. I did get to other pics communicating but when i try it with the cc1000 pic it doesn't work.
On the oscilloscope there is a output from rc6.

You must use set_tris for serial port. I've seen problem with out using it.
