WHAT The LANdon Bridge IS
=========================

The LANdon Bridge is a software bridge/repeater/router for Artisoft(R)
LANtastic(R) networks. It allows users to mix and match supported hardware
types on their LANtastic(R) network, and allows all network nodes to log
into all servers and send messges to all nodes, regardless of what kind of
hardware they are using.

Users of the LANtsatic(R) 2Mbps adapters or the LANtastic(R)/Z network can
connect to each other or to a 10Mbps network segment, such as Thinnet or
twisted pair, and not be subject to the usual hardware restrictions of
such an arrangement. See MANUAL.TXT for more details.

The LANdon Bridge is a product of Limerick Software, Arcata, CA, and
is NOT a product of Artisoft, Inc. No endorsement of this product has
been made by Artisoft, Inc.



TIME-RESTRICTED VERSION
=======================

This version of The LANdon Bridge is intended as a shareware demonstration
program. It is a fully functional copy of the registered version of The
LANdon Bridge, with one exception.

After approximately 1 hour of operation, it will execute the SHUTDOWN command
internally. The SHUTDOWN command is documented in the manual. After the
initial 1 hour of operation, the RESTART command will not succeed.
The FLUSH and REMOVE commands will still work, however, so you can cleanly
remove the demonstration program from memory, even after the 1 hour
demonstration period has expired.

Note that there will be no warning before the SHUTDOWN command is executed
internally. Workstations may have to be rebooted, and data may be lost if
they are actively accessing servers via the bridge when a SHUTDOWN occurs,
depending on the particular application program's response to the loss of
connection with the server.



CHANGES FROM VERSION 1.0
========================

The following features have been added:

*The RUN_BURST switch has been added. The valid range
for this switch is from 2 to 127 ticks. The default
is 8. This value dictates the longest period the bridge
will process requests before yielding to the system. It
only takes effect during periods of heavy network traffic
across the bridge.

The following problems have been addressed:

*Switch settings causing a DOS out-of-memory condition
would lock the machine up in version 1.0. Now, the
error will be reported properly and the program will
return to DOS.

*If VERBOSE was the only command-line switch invoked,
and an error ocurred while installing version 1.0,
erroneous VERBOSE information would be output,
but the error message would not. Now, the VERBOSE
output will not occur if there is an error, and the
error will be reported.

*Installing version 1.0, REMOVE-ing it, and re-installing
it a second time would cause the addition of erroneous
names to the NetBIOS name table of each adapter in
the bridge machine. This will not occur in version 1.0a.

*Version 1.0 would not recognize some Artisoft(R) 2Mbps
adapters. Version 1.0a now recognizes these adapters.

*Quasi-circular network topologies, such as when a bridge
machine with three adapters is connected to another
server on the network on two of those adapters (the
other server has two adapters in it), would cause
various problems and lockups. Similar problems would
arise if there were different machines on different
bridged network segments using the same machine name.
Version 1.0a is much better prepared to handle the
NetBIOS name conflicts which arise under such conditions.

*The ADD_SERVER_NAME switch returned incorrect error
messages in some situations. Version 1.0a should
report correctly now.

In addition, the following internal changes have been made:

*A local stack has been provided, rather than relying upon
the foreground task's stack.

*All NetBIOS POST routines are now queued for execution
during the timer tick interrupt, rather than at the time
NetBIOS calls them. While performance may suffer a bit
as a result, this makes for a much more stable NetBIOS
environment.

*The code for adding and deleting NetBIOS names has been
restructured considerably.

*The size of the buffer used when emulating a workstation's
REDIR has been increased to match that used in LANtastic(R)
Version 5.0. The new value works for previous versions
of LANtastic(R), as well.

*The default value for the REQUEST_SIZE switch has been
changed from 14 to 32, to reflect the change in the
SERVER.EXE default between LANtastic(R) Version 5.0 and
LANtastic(R) Version 4.x. The maximum value for this
switch has also been changed, from 2048 to 32767. While
Version 5.0 of Artisoft's SERVER.EXE accepts a REQUEST_SIZE
as large as 65535, Version 1.0a of BRIDGE.EXE can only go
as high as 32767.


CHANGES FROM VERSION 1.0a
=========================

The following problem has been addressed:

*Due to a bug in the microcode of some 80286 chips, versions
1.0 and 1.0a would cause some 286-based machines to lock
up on occasion. This problem has been resolved in version
1.0b.


CHANGES FROM VERSION 1.0b
=========================

The following problem has been addressed:

*There was an incompatibility with version 4.06 of Artisoft's
AILANBIO NetBIOS driver that caused error messages reading
"Network node MACHINENAME is not listening." This has
been resolved in version 1.0c.



CHANGES FROM VERSION 1.0c
=========================

The following problem has been addressed:

*There was an incompatibility with version 4.06 of Artisoft's
AILANBIO NetBIOS driver that caused error messages reading
"Too many redirections or logins to node MACHINENAME" the
first time a particular machine attempts to login via the
bridge machine. This has been resolved in version 1.0d.



KNOWN PROBLEMS
==============

To the best of our ability, all known problems with The LANdon Bridge, version
1.0, have been addressed. The following guidelines should be followed to help
insure a stable network environment:

*When running AILANBIOS.EXE, make sure that each machine
on a given network segment is using the same values for
the INITIAL_SEND_SIZE and SIZE switches.

*When running LANBIOS.EXE, LANBIOS2.EXE, or LANBIOS3.exe,
make sure that each machine on the 2Mbps network segment
is using the same value for the BUFFERS switch.

*Whatever NetBIOS drivers you are using, make sure that
there are ample NAMES, NCBS, and SESSIONS allocated
for each adapter in the bridge machine. A good value to
use for each is 32.

*When running REDIR.EXE, make sure that each machine on each
network segment is using the same value for the SIZE switch,
and that that same value is used for the BRIDGE.EXE
BUFFER_SIZE switch.

*When running SERVER.EXE, make sure that each server on each
network segment is using the same value for the
NETWORK_BUFFER_SIZE switch. If the REDIR.EXE SIZE switch
value is different from the SERVER.EXE NETWORK_BUFFER_SIZE
switch value, then you may use the SERVER.EXE
NETWORK_BUFFER_SIZE switch value for the BRIDGE.EXE
BUFFER_SIZE value, rather than using the REDIR.EXE SIZE value
for the BRIDGE.EXE BUFFER_SIZE. This will result in increased
bridge performance. Note that both REDIR.EXE and BRIDGE.EXE
require the value be in bytes, and that SERVER.EXE requires
the value be in kilobytes. Be sure to make the appropriate
translation.

*When running SERVER.EXE, also make sure that each server on
each network segment is using the same value for the
REQUEST_SIZE switch, and that that same value is used for
the BRIDGE.EXE REQUEST_SIZE switch.

*If you experience system lock-ups of the bridge machine, try
using switch values to increase the size of the bridge's heap.
A good way to do this is to increase the number of LOGINS on
the BRIDGE.EXE command line.

*If you experience problems with the nodes accesing servers via
the bridge, then try increasing the number of TASKS on the
BRIDGE.EXE command line.


TO REPORT BUGS OR OTHER PROBLEMS
================================

You can send bug reports to us at the address given below, or you can contact
the author of The LANdon Bridge, Jim Welsh, via CompuServe(R) at 71302,2423.
Please be as detailed and as patient as possible. We will respond to all bug
reports as soon as possible. While we will try to respond individually
to bug reports, if the volume regarding a particular class of problem dictates,
we may respond by form letter or equivalent.

When reporting bugs, please provide as much information as possible about
the network activity leading up to the problem. Please include printouts
of your CONFIG.SYS, AUTOEXEC.BAT and STARTNET.BAT files, or their equivalents
for your system.

Also, describe or illustrate your network topology. The more information
we have about your network environment, the easier it is for us to solve
your problem.

Please indicate whether the bridge machine is having the problem or if it is
the nodes accessing the bridge, or the servers being accessed, and whether it
is affecting other nodes on the network. Indicate which versions of the
various network programs are being used, since this infomation is not
necessarily available from STARTNET.BAT alone. If you use the @switchfile
option with network programs, please include printouts of the switchfile as
well. STARTNET.BAT printouts from a typical workstation from each network
segment would be helpful, as well.
