Hello,

You can simply change these port in the #use rs232.
here is an example:

You asked exactly this question only a few days ago.
The same answer applies.
You can use _any_ pin for RS232, but unless you use the hardware pins, you have to live with the restrictions of _software_ RS232. No buffering in either direction, to receive, your code _must_ be waiting for the characters as they arrive.
