Message-ID: <298@indri.primate.wisc.edu> Date: 22 May 89 13:59:05 GMT Organization: UW-Madison Primate Center Lines: 10 Do devices exist that can be put on a phone line to indicate whether the line is already in use? This would be used in a situation where two people in a home each have a modem, and one wants to know if the other is on, without picking up a phone to find out. All that would be necessary is a little thing with an LED. Thanks, Paul DuBois dubois@primate.wisc.edu rhesus!dubois bin@primate.wisc.edu rhesus!bin
