Hello all you good people:
I am looking for a schematic that will recognize when a computer connects to a phone line Weather I am on the Phone or when the line is open or not in use. I was wondering if there is a simple solution like detecting a fax ring or modem. :? When you have a fax machine it can distinguish between a voice and a fax. How do they do this? Maybe this is the approach that I must use. Any way any suggestions will be of great help. I already have an off hook led that lights every time a call is being received or the line is in use. and what I want to do is to have a blue light led to light when a fax or a computer comes on line on the same phone line. Thank You for any information. Have a Merry Christmas and a Happy New Year. fredje1@joimail.com
