One thing to consider is that this pin may have several other uses and nornally you have to specifically 'disable' those functions. Perhaps this is part of the problem?
As an example...some PICs have the 'comparators' defaulted on and you MUST specifically disable them.
just an idea..

Have you turned off TXEN?.
Otherwise it will be driven high by the UART. |

Yes. Also in the LST don't have routine for tx

No.....
Read the thread I pointed to.
To use the TX pin as a normal pin, you have to disable the TXEN bit. The thread shows how to do this. |

Thanks again Ttelmah 
I wish CCS was giving such information (or maybe I miss it)
It works perfect!!!
Even the RX pin works fine, should I do the same thing for it?
| Code: | | #bit RXEN=getenv("BIT:RXEN") |
& in the main
