I am searching for a modem that will call back a pre-assigned phone
number when it is called. I am looking for it in regards to trying to
make a dial link more secure by having the local end call a modem. The
modem answers, then hangs up and calls the preprogramed number to run
the communication over.
If anyone knows of a modem that has this ability could you please let
me know? Thanks in advance for any information. My email address is:
smh@hrmso.att.com or att!hrmso!smh
Thanks again.

There is a unit called the secure access multiport (SAM) manufactured by a company named LEEMAH we have two of these units at work that have never been used primarily because of a) the need for someone to actively manage the device (check reports, change numbers e.t.c) b) The need for users to switch their modem from originate to answer to use the device, and c) A number of users need access from a wide variety of locations. Also, with any device that does this type of thing you would want the incoming and outgoing lines separate otherwise the caller might hold the line (by not hanging up) and the device is then fooled into thinking it called a new number when in fact the line has never been released. My 1984 technical manual for the SAM does not list a phone number or address for LEEMAH or I would include that information here.
