IBM 16/4 Token-Ring manual TxPriMax, Valid values 0 to

Table 9. DOS and OS/2 NDIS device driver parameters in PROTOCOL.INI (continued)

Parameter	Explanation
LoopBack	Determines whether or not the adapter will copy a frame that it is transmitting if the
	destination address is recognized by the adapter.
	Valid values:
	Yes	Indicates that transmit frames whose destination is this adapter will be transmitted
		and then received by the adapter.
	No	Indicates that transmit frames whose destination is this adapter must be looped
		back by the protocol stack.
	The default is No.
TxPriMax	This parameter specifies the value of the maximum token access priority that will be allowed
	for frames sent on the high-priority transmit channel. High-priority transmit frames whose
	Frame Control priority value exceeds the value of this parameter will have their token access
	priority reduced to the value specified by this parameter. Frame Control is a field in the IEEE
	802.2 Logical Link Control (LLC) header.
	Valid values: 0 to 6
	The default is 6.
TxPriThresh	This parameter specifies the frame priority value that will be used to transmit on the
	adapter’s high-priority transmit queue. IEEE 802.2 LLC frames that contain a frame priority
	setting (in the Frame Control field) that is equal to or greater than the value of this
	parameter are treated as high-priority frames.
	Valid values: 1 to 6
	The default is 1.
LLCOnly	This parameter indicates whether only LLC frames should be copied by the adapter when it
	is running in promiscuous copy mode. If this parameter is set to Yes, no MAC frames will be
	copied while in promiscuous copy mode.
	Valid values:
	Yes	Copy only LLC frames.
	No	Copy all frames on the ring.
	The default is No.
EOIDelay (OS/2 only)	This parameter should always be set to zero. It is intended for debug use.

Valid values: 0 to 10

The default is 0.
