Is the device running your firmware? And what happens when the host crashes completely? > Any suggestions are much appreciated. I have to say I'd be tempted to do the reverse. Ping the device at a regular interval with a vendor packet from your control panel app (or similar) and have it shut down if nothing is received after said interval has elapsed. > Jake BR, Jerry _______________________________________________ Do not post admin requests to the list.
