Having a bit of a problem... 2x 56K PCI modems in 2x W2K boxes. Dial out no problem, send faxes etc. fine and dandy. I need them to auto-answer though and it won't!

The app that will be using it is Winfax, but I'm trying hyperterminal also and no joy there either.

Hyperterminal direct to com4,
at&f
OK
atd 01234 567890
OK
at s0=1
OK

phone that line from my moby, hear it ringing (thru phone not modem speaker), modem does nothing (expecting to see RING RING in hyperterm)
hit ata at this point, modem picks up and squeals at me.
But it won't see the line ringing and pick up by it's self

This is two PC's in two different buildings with two different modems, one modem replaced with new. the only common thing I can see is they're both hanging off mod-taps & the buildings structured cabling.

What am I missing?

Ignore the cabling, the fact that it says ring tells you the signal is getting through to the modem.

Is anything else configured to use the modem?

Have you done an AT&F after placing your calls to reset the modem?

Its the cabling (probably).

If your BT lines are wired straight into the cat5 (not from a BT master socket with adaptor) then you need the master version of the mod tap adpator at the modem to generate the ring signal. If your BT is wired direct to cat and you have the non master modtap it doesn't ring but will still pickup when you do ata.

42-111 = master (peer in the socket end you will see the capacitor)
42-114 = non master (no capacitor)

Hope that makes sense

Whoops, I read that as Hyperterminal was saying "ring". Yup, probably a slave/master issue.

Will procure one of these 'master-taps' and give it a whirl

Thankyou!
