Network Driver Optimization

This setting specifies whether to optimize the network driver
for a DOS client, a Microsoft Windows or IBM OS/2 client, or a
server environment. Changing this option to match your
system may improve the network performance. The response
time of your system in performing network tasks may also
improve.

Maximum Modem Speed

Selecting a modem speed tells the adapter how long it can
disable interrupts without causing problems with the serial
port. The lower the modem speed, the longer the adapter
can keep interrupts disabled.
On slower computers, running with longer disabled
interrupts can improve network performance. On those
computers, changing the option setting to 2400, 1200, or No
Modem may improve performance.
On faster computers, there is little performance difference
among the settings.
If you experience problems with your modem, such as
dropped characters or excessive retries, selecting a higher
option setting should help.
If the problem is not due to the 3C589C adapter, changing
the option setting will not make a difference.
CAUTION: The default value (9600 baud) will work whether
you have a modem or not, or even if the modem is slower
than the default (for example, 2400 baud). Do not change the
default option setting unless you experience problems.
If you experience compatibility problems between your
adapter and another device in the system other than a
modem, selecting a higher option setting may help.
