It was suggested (and a good suggestion it was) to add support for using a
Parallel Printer Port to do I/O, including PTT, COR, CTCSS, and general-purpose
uses if you have some need to do so.
It will be available in SVN after 21:15 PDT this evening. If you are interested
you will at least need to get a new copy of chan_usbradio and app_rpt.
Please see http://app-rpt.qrvc.com/node/177 for documentation reflecting
these changes.
