You are describing a case where you have an existing application flow: Serial port to POS.

And you want to put monitoring place to see what that serial traffic looks like. So you don't want to replace or modify the existing code but rather just see what is happening.

So you should google for the following

windows serial port intercept


That said however I would suggest that if the POS code is under your control that the POS code itself should be modified to provide the same sort of monitoring. Log files (search for libraries) can both be used to control and collect such data.
