How to get around "port busy" error

edited May 2017 in Arduino

Hello all,

I am working on a project in which I am using an Arduino attached to an XBee to send data to an XBee that is attached to my computer. I am then trying to use processing to intercept the data that the XBee at the computer is gathering. However, the port that the XBee is plugged into is always in use gathering, and thus never has any chance to send it to processing. I was wondering if anybody knew a work around for this? I have working processing code to gather data directly from the Arduino (no XBee involvement) with no "port busy" error.

Thank you for any insight you may have!
