The script started QLGT and monitored the file for a change. On a change it sent a character to stdin. I think this was on Linux. Thus I am not sure if you can do the same stunt on Windows.</div> <div> </div> <div>Alternatively, if your phone is connected wie Bluetooth creating a virtual serial port that outputs NMEA data, you can connect QLGT directly to your phone.</div> <div> </div> <div>HTH</div> <div> </div> <div>Oliver</div> <div> <div name="quote" style="margin:10px 5px 5px 10px; padding: 10px 0 10px 10px; border-left:2px solid #C3D9E5; word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;"> <div style="margin:0 0 10px 0;"><b>Gesendet:</b> Sonntag, 22.

What I wanted to say was -- monitor 0 works as I expected and Oliver described - activity on the keyboard will cause the data file to be read again, applying any route updates. What I want to do is get qlandkartegt to apply data updates to a .gpx file without having to do any keyboard activity. I'm sending gps location information from my phone while out walking. This is relayed to my PC which updates a .gpx file and I'd hoped by linking the .gpx file to a specific file descriptor and using --monitor FD, qlandkartegt would re-read it and the map would show the route being taken. <div> </div> <div>I have got the desired functionality by killing qlandkartegt when new data arrives and re-running it with the updated .gpx file but it does seem rather inelegant.</div> <div> </div> <div>Thank you for the help.</div> <div> </div> <div>Best wishes</div> <div> </div> <div>Ben Weston</div> </div> ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
