I connect the pin 2,3,5 with pic pin 25,26 and ground (normal and cross)
Post which pic you are using. You must have a Max 232 in between your pic and your TC35.

The max232 you have internally the TC35 is for converting the internal TTL to rs232. You will need an additional Max232 for reconverting the RS232 to TTL for your pic. See my last schematic for connection from your pic to TC35 DB9
