Why does my
modemkeep dropping connection?
AzNET's terminal server will drop your connection only for excess idle time. There is nothing about the Internet that will cause modem disconnects. But any number of problems can occur between your modem and ours.
Modem brands are not entirely 100% compatible. A modem initialization string that works well for connecting your modem to a USR, for instance, may not work for establishing a problem-free connection to a Hayes. A simple change in the initialization string will often fix that problem.
Furthermore, some modems (such as certain older models of the USR Sportster) have bugs. For instance, one version of the Sportster will drop carrier if the connect speed drops below a certain level.
Port speed also matters. Setting it above the recommended level can cause problems.
