[net.followup] call back

pickett@ecsvax.UUCP (10/31/83)

Does anyone know of some good call-back systems for dial-up networks?
I understand there is an article on the Leemah system in this month's
issue of Byte, but I haven't seen much on other systems.  Your thoughts
on this would be appreciated.

                             Many thanks,
                             Mike Pickett
