Introduction
The LAN-Modem permits devices that require dial-up modems
for communicating to use the Intranet or Internet instead of the
telephone system. On a serial interface, the LAN-Modem
behaves in a way this is compatible with standard modems for
the telephone system; the only difference is that the dial-up
number is replaced by an IP address.
