AL >>Would anyone have any idea how I could connect two modems together,
while NOT using the telephone system?? I have tried but it doesn't seem to
work!<<
Ok, you can hook the two modems directly by running the phone cord
directly between modem bypassing the phone company. However, the
phone company also provides power over one of the lines to power the
phone. This is why the phones still work when there is a local
blackout.
Some modems also provided enough power to allow direct connect to
another modem, but some don't. If you need more power try this:
Get a 9 volt battery (the type used with clock radios). Cut the RED
wire of the phone cord, and splice the battery into the RED wire. One
half of the wire to the positive, the other half to the negative – so
the transmissions pass through the battery.
Only the RED & GREEN wires are used for most phones, the BLACK &
YELLOW are spares for a separate line.
You might be able to find a 9 volt battery connector (clamp?) at
Radio Shack, or out of an old radio. Slicing the RED wire with the
connector will allow easy replacement of the battery.
You will need to set one term/modem to auto-answer (ATA), then call the
other term/modem with a simple "ATD". If you have high speed modems, you
may want add the extra options to the dial string. The phone number is
only needed by the phone company to route the call to the other modem.
