How to use serial terminal software with PIC18F26K20?

Hello,
Please could i ask how to use Realterm serial data acquisition program?
We want to load the debug output of our microcontroller to a file but we are not sure how to do this.
We have a PIC18F26K20 on a PCB , and we have connected to GND and the TX pin (pin 14) of PIC18F26K20.
The software engineer has loaded data into the PIC which will give debug data from inside the micro.
We need the data to see where the micro is going wrong in its software.

We know that we need "19200 bits/second, and 8 bits, parity , none"...we can see where to set that but not where to get the data downloading from the PIC to our PC

Do you have a "TTL to RS232" IC connected to pin 14?
Do you have a old PC with serial ports?
Do you have a "TTL to USB" converter/cable?

we have just ordered a TTL to USB converter cable. We hope that we just plug the USB into the PC and the realterm window will start doing its stuff and package all the data up for us and put it in a file somewhere, so we can give it to our software engineer....when they start working here

I'm sure I already answered this in your other thread!!
