[comp.dcom.modems] modem help needed

tmhoff@uokmax.ecn.uoknor.edu (Thomas Milton Hoff) (08/12/90)

I recently acquired a Zenith 2400 baud modem without the power adapter.  Can
anyone tell me where to order one?  I believe it is the same jack as the 
Hayes modems.  (Dang thing costs $40 from Zenith)
The jack looks like this:
 /-----
/     |
|     |
-------   and has 3 prongs inside.
I thought about replacing the jack with a normal size, but the back of the
jack says 8.5V.  Will it hurt to hook 9 to it?  What are each of the 3
prongs for?

Thanks for the Help
