Lucian, Another debugging option is to use gpsim's LCD module. Recent enhancements to gpsim and the LCD module have yielded a very accurate simulation environment. Since you're using Outlook as your email client, I assume that you're using Windows. At the moment, gpsim doesn't work with the LCD module under Windows. It only works with Linux, BSD, and other Unix based OSes. The good news to you (and the other 98% of the PicList members) is that gpsim almost completely works under Windows (thanks to Borut Razem). I estimate that before the end of June a new release of gpsim will be made and Windows will be fully supported. Meanwhile, you can take a look at: http://www.dattalo.com/gnupic/gpsim.html http://www.dattalo.com/gnupic/lcd.html Scott -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
