Using Internet Connections

This chapter uses an example to demonstrate how to configure the PortMaster to
establish a continuous connection to an Internet service provider (ISP), shown in
Figure 18-1. This connection creates a gateway from your office to the Internet using a
dial-out connection through one of the serial ports on your PortMaster. Internet
connections can also be set for on-demand operation.
