RE: [SA-list] Telephone Lines Monitoring

[Michael D. Shook]

I would start looking closely at the Hayes Modem command set. This is the "standard" "ATxxx" commands most modems use. You can play around with how a check might be written by starting a telnet session to the COM port the modem is on, then issuing the commands by hand.   http://www.modems.com/general/extendat.html for a good place for the most common stuff, http://www.modems.com/glossary/extend1f.html might be the way to go.   Also, the manual for your modem should have all the AT commands it supports listed.   Michael D.

If it gets an engaged signal or no dial tone then the check would show as down.   Is anyone doing anything like this or have any suggestions how how it could be done?   Cheers   Stephen
