PROSet runs when you highlight an adapter and click the Properties button in
the Network control panel.
Duplex Mode (Optional)
Duplexing is a performance option that lets you choose how the adapter sends
and receives data packets over the network. The adapter can operate at full
duplex only when connected to a full duplex 10BASE-T or 100BASE-TX
switch, or to another full duplex adapter.
The possible settings for duplexing are:
• Auto (requires a full duplex adapter or switch with auto-negotiation capa-
bility). The adapter negotiates with the switch to send and receive packets
at the highest rate. This is the default setting. If the switch does not provide
auto-negotiation, the adapter runs at half duplex.
• Full duplex (requires a full duplex switch or adapter). The adapter can
send and receive packets at the same time. This mode can increase adapter
performance capability. If the full duplex switch provides auto-negotiation,
the adapter runs at full duplex. If the full duplex switch does not provide
auto-negotiation, you need to set the adapter duplex mode manually (see
the following sections), because it defaults to half duplex.
• Half duplex. The adapter performs one operation at a time; it either sends
or receives.
