CM8880/MT8880 transceiver

What exactly is your problem? Have you actually built the circuit?
If you have have you tried your code and found a specific problem?
I think you have had no answers because you have not asked a specific question, try your code and if it does not work then tell us what it is or is not doing.
 
Shufa,
I haven't looked much at your code, but I noticed on your schematic that you've left the MCLR pin of the PIC floating. You need to tie it to Vdd with a 10K resistor or erratic operation will result.
