Hi,
I'd like to use my modem to wake up my PC, but the modem sets the Ring Indicator as soon as the phone rings. Ideally I'd like it to wait for, say, 20 seconds and only set the Ring Indicator if the phone is still ringing.
So I thought maybe I could put some kind of circuit between the modem and the PC which would block the RI line unless the RI line had been set for 20 seconds or more. Can anyone suggest how this might be done?
Thanks,
Hajo
