3Com 3C319 Auto Ring Speed Detection, Natural Packet Interval, Disable Receive Packet Buffering

7-8CHAPTER 7: CONFIGURING DYNAMICACCESS CLASS OF SERVICE

To prevent this problem, the driver uses a ratio value to periodically send out a low-priority packet (if one is waiting to be sent).

For example, if a value of 1000 is entered, one low-priority packet would be sent for every 1000 high-priority packets. A value of 25 is recommended for most applications.

Auto Ring Speed Detection

An alternative way to access DynamicAccess Class of Service is to click the Properties button with the 3C319 NIC selected while you are viewing the adapters list. Using this method also allows you to disable or enable the auto ring speed detection option.

The auto ring speed detection option permits the NDIS 4 driver for Windows 95 and Windows NT to detect and operate at the current ring data rate. Auto ring speed detection is automatically enabled when you load the NDIS 4 driver. (This feature is not available with other 3C319 NIC drivers.)

To manually set the ring speed after disabling auto ring speed detection, see “Changing Configuration Option Settings” in Chapter 5.
