Another thing this is good for is remote server support via dialup as an emergency backup. The main remote server box is on the network... and a "secondary" access box sits next to it (connected via serial link) with dialup access. When the network backbone is down for some reason... or the tech needs to take the main machine off-line via remote, she can dial into the access box and then run minicom into the main server (the access box acts as a terminal). Direct phone access is not permitted on the main server... and the access box is not on the network.
I understand you can convince some modems to only answer when the incoming call id is a certain number; ie, you can dial to it only from a certain phone. In this way, you can connect the modem directly to the supervised machine. The other technique is call back: when dialled, the modem will hang and call back a preconfigured number, the one of the technicians. - -- Cheers, Carlos E.
