Configuring the TCP/IPThe TCP/IP configurations can be made manually to the communicator’s Internet access point settings.Automating the configuration can make this set-up more user-friendly.The communicator uses IPCP (rfc1332), DHCP (rfc1541), and /or BOOTP (rfc951) for IP-address negotiations.The dial-in system should provide Microsoft extensions for IPCP DNS negotiation (MSIPCP), BOOTP-server, orDHCP-server for automatically configuring the communicator’s other TCP/IP settings, such as the DNS server.The TCP/IP settings can also be sent to the communicator using a special short message containing Internetaccess information, such as username, password, phone number information and scripts. The format of thesespecial short messages is presented in Using the Special SMS Features at http://www.forum.nokia.com.2.3.
