358 Installation Guide for Clients

trxbufsize

Specifies the size of internal transmit and receive buffers. Increasing

this value is required only when running applications that use Group

SAPs or that issue transmits containing more buffers than the media

access control driver can accept in one transfer call.

uipackets

Specifies the number of data descriptors to allocate for sending UI-

frames.

unload

Specifies how to unload Microsoft DLC from memory. This value

should not be changed.

usedix (Ethernet only)

Sets the frame format. Set to zero (the default) for 802.3 Ethernet

format. Set to 1 for Ethernet DIX 2.0 (Ethertype 0x80D5) format.

(Ethernet DIX frames have an extra type field instead of the length

field.)

windowerrors

Specifies the number of dropped packets that the adaptive window

algorithm allows before it decreases the send window. (For more

information on the adaptive window algorithm, see the adaptrate

entry in this section). For example, if windowerrors has a value of 1,

one packet can drop between runs of the algorithm without having

any effect; if 2 packets drop, the algorithm decreases the send

window. Keep the value of windowerrors low for a lightly loaded

network, and increase it for a heavily loaded network.

xsaps0

If xsaps0 is defined, then during the dir.open.adapter call for

adapter #0, this value is compared to the maximum value for saps

specified by the application program and the larger of the two is used.

This is used when you need to run more than one Microsoft DLC

application. The sum of xsaps0 + xsaps1 must be less than or equal

to the value for saps. Increase saps if necessary. For example, if you

want to use two Microsoft DLC applications and each requires two

SAPs, you define xsaps0 = 4. When the first application issues the

dir.open.adapter call, it would ask for two SAPs but would get four

SAPs because of this parameter. This way the second application

would have enough SAPs to run.

xsaps1

Similar to xsaps0, but for adapter #1.

xstations0

Similar to xsaps0, but used for changing the number of link stations,

rather than the number of SAPs. The sum of xstations0 + xstations1

must be less than or equal to the value for stations. Increase stations

if necessary.

xstations1

Similar to xstations0, but for adapter #1.
