On which chip? Let me quote from the 16C7x data sheet:
-------------------------------------------------
Bit SPEN (RCSTA<7>), and bits TRISC<7:6>, have to
be set in order to configure pins RC6/TX/CK and
RC7/RX/DT for the Serial Communication Interface.
-------------------------------------------------
Notice it says "set" not "clear".

I was bitten by this the first time I tried to transmit on a 16C74A, so I
remember it quite well - I have no idea how you made it work the other
way, but "it works for me the way the book says" :-)
