Configuring and Testing the PCLTA-21 Card
20
For Windows 98, the term “Layer6 Buffering” refers to the same parameter as
Uplink Buffering. There is also a “Layer2 Buffering” setting that should
always be left at its default value of 20.
PCLTA-21 Diagnostics
A number of diagnostic and testing services are provided by the PCLTA-21
control panel application. Clicking the Diagnostics button in the main control
panel window displays the PCLTA-21 Diagnostics dialog. This dialog contains
buttons for the diagnostic commands and displays the version number and
current status of the PCLTA-21 device driver. If no PCLTA-21 card is installed
in a PCI-bus slot, the Diagnostics window will display “(no driver found)”.
