ABSTRACT:
This version of TRXNET.LAN v2.0 fixes a bottleneck problem on a LAN with
multiple file servers.  If a server goes down on the LAN, workstations
trying to communicate with the server through a bridge will execute a retry
command, and clog the network.  Symptoms of this problem include Abort
Retries at the workstations.

This README file of TRXNET.EXE accompanies the TRXNET.LAN for NetWare
v3.1x.

Problem:
This version of TRXNET.LAN v2.00 fixes a bottleneck problem on a LAN with
mutilple file servers.  If a server goes down on the LAN, workstations
trying to communicate with the server through a bridge will retry, and
"clog" the network.  Symptoms of this problem include Abort Retries at the
workstations.  Additionally, users may be unable to login because the
Packet Receive Buffers have reached the Maximum limit.


Solution:
This new TRXNET.LAN changes the MaxRetries from a default of 10 to 0. There
is little need to keep retrying a send to a node that does not respond in
any way to the Free Buffer Inquiry.  While the driver/card is retrying the
packet, all other sends to the driver are being queued.  Thus, the Maximum
Receive Buffer count may be driven up on busy networks where packets are
being routed internally to the ARCNET card. This may cause a bottleneck in
the system.


Installation:
1)  Copy TRXNET.LAN to your NetWare system start-up area (SYS:SYSTEM and/or
DOS partition). Be sure to rename the old version of the TRXNET driver.

2)  Load the driver as you normally would on your system.


Note: If needed, the Max Retry default may be changed during load time.
