Monitoring the LAN LEDs

The status LEDs on the network connector are used for
verifying the integrity of the link between the LAN+Modem
card and the network hub (Figure 10, Table 1). The PC Card
must be connected to the network (see Chapter 2) and
the network driver must be installed (see Chapter 3).
