Pinouts.ru has whole page listing just serial cable pinouts, here:

http://pinouts.ru/SerialPorts/

There are number of those that end in a RJ45 connector, but it is a small number, probably less than 10. So you should look at that page, and see if any of those look familiar to you.

Then you need the datasheet for the specific POS you have, RJ45 serial is not a standard.
