Why can NetModem Client immediately report a broken network connection to the application?
Depending on its configuration on your network, the keep-alive feature of the TCP/IP protocol takes a long time (10 to 15 minutes) to differentiate between a merely idle connection and a broken one. The TCP protocol opts to err on the side of keeping a possibly idle connection open. To improve on this, NetModem Client and NetModem Server use a separate mechanism to detect lost connection in approximately one minute.
