RE: Re: How do I tell whether the phone's ringing?

["Mark Harrison" <Mark.Harrison@xxxxxxx>]

Ian,

I guess that the appropriate line on a modem is the best way.

I would have thought that with a 5 second delay, then there was no fancy
HV programming to be done. The "gone low" would mean  "it's
rining now",
and the "gone high" would mean "it's stopped"  = Have I
understood
correctly?

Regards,

OK Mark

As the delay unit stands it accepts a +ve signal as a trigger and has a
delay adjustable from almost nothing to about 5 seconds. Assuming it is
triggered by either the phone line itself via an optocoupler (chip
thingy)
or through the modem ring line it can bring an HV input port low for the
delay time set. This will give HV time to notice the port change of
state
even if it is doing something else for a short while and do whatever is
programmed. I guess the only thing to program round is multiple triggers
if
the delay is short. More detail on this another time but it is easy to
program round with a timer.

Let me know how you want to connect it and I will think about how to do
it.

Ian
