LANtastic Network Operating System Version 4 Compatibility Bulletin
Product Reviewed: Pathway/Access Release 2.0 and WIN/ROUTE Release 2.1 by
The Wollongong Group
Classification: TCP/IP Connectivity
Date: 06/22/92
Engineer: JAG
-------------------------------------------------------------------------------

Compatibility Statement:
Pathway/Access Release 2.0 and WIN/ROUTE Release 2.1 are compatible with
LANtastic NOS 4.xx.

Product Overview:
The Pathway/Access and WIN/ROUTE products can be used together to provide
TCP/IP connectivity between a PC-based LANtastic network and a variety of
machines that are connected on an Internet network. A dedicated PC running
WIN/ROUTE provides the link between the LANtastic and the TCP/IP world,
while Pathway/Access provides TCP/IP transport layer and applications services
for the LANtastic side of the link. In general, the Pathway drivers convert
LANtastic's standard NetBIOS packets into TCP/IP format, allowing IP-based
applications to establish links via the WIN/ROUTE router. We tested and found
compatible the TELNET terminal emulation program, FTP file transfer utility,
FTPD file transfer server, PING network communication test, LPR remote
printing utility, and the Berkeley R-series commands RCP (remote copy), RSH
(remote shell), and RLOGIN (remote login).

Test Equipment Configuration:
The following machines were used for Pathway/Access-WIN/ROUTE testing. All
machines running LANtastic used Artisoft AE-2 or AE-3 NICs and testing was
completed using LANtastic NOS v4.1. Machines running as LANtastic peer-to-
peer servers are designated by (S).

- CompuAdd 325: 386DX/25, MS-DOS 5.0 (S)
- Tandon 486/33: 486DX, MS-DOS 5.0 (S)
- Northgate 386/20: 386DX, MS-DOS 5.0 (WIN/ROUTE host)
- Altima 286: 286/16 portable, MS-DOS 4.1
- Clone 286: 286/12, MS-DOS 3.3
- CompuAdd 333: 386/33, SCO UNIX System V/386 Release 3.2 v2.0

A Western Digital WD8003E network adapter was the network interface for the
UNIX system. The dedicated router used both an AE-2 and a WD8003E card to
route packets between the DOS and UNIX systems.

Installing and Running WIN/ROUTE:
Installation of both Pathway/Access and WIN/ROUTE is accomplished by
running a batch file included on the installation diskettes. We recommend
installing WIN/ROUTE before installing Pathway/Access, since the router must
be operating properly before TCP/IP services can be used from a LANtastic
station. The router PC must be dedicated to the function of routing and cannot
be used as a LAN workstation. It requires two LAN adapter cards, one for the
LANtastic side of the network and one for the TCP/IP side. In the example
depicted in Figure 1 above, the LANtastic interface card is an Artisoft AE-3
adapter and the Western Digital WD8003E card is used for the TCP/IP interface.
WIN/ROUTE installs to a directory called WINTCP from a single program
diskette. The install routine appends the following line to the CONFIG.SYS
file:

DEVICE=C:\WINTCP\WINTCP.SYS

The WINTCP.SYS driver is really a data structure that holds configuration
information for the routing TCP/IP kernel, ROUTETCP.EXE. Before the kernel
can be run for the first time, this information needs to be configured, or
"customized," via the CUSTOM program. The WIN/ROUTE documentation
covers the appropriate values for the configurable parameters, but there are
some that must be set to specific values. These are:

1) Set the number of interfaces to two (2). This number is the number
of network adapter cards that are installed in the router.

2) Set the Internet (or IP) address for each interface. The actual
addresses depend on what IP addresses are assigned to the site. If
there are no IP addresses officially assigned to the site and the LAN
will not be connected to a larger network, these addresses can be
arbitrarily determined. You must, however, make sure that the correct
IP address is assigned to its proper interface number. See the
"Hardware customizing Procedure" section in Chapter 2 of the "WIN/ROUTE
Installation and User Guide" for details. Refer to the WIN/ROUTE and
Pathway/Access documentation for general information regarding IP
addressing.

Once customization is complete, reboot the PC to effect the new configuration.

Starting the router is a matter of running the drivers for the adapter cards and
then bringing up the routing kernel and software. As mentioned above, the
router must be a dedicated machine. In the protocol stack shown in Figure 3 on
page 2 (Protocol stacks are read from the bottom up, lowest level drivers at the
bottom to highest level at the top), the AEX.EXE and AILANBIO.EXE TSRs are
loaded as the basis of the LANtastic network interface. Wollongong's
NB_DRV.EXE is loaded on top of them in order to provide NetBIOS to IP
translation for the kernel. The other interface - via the WD8003 adapter - is
pure IP, so Wollongong's WD80X3.EXE TCP/IP driver is all that is needed. The
ROUTETCP kernel is then loaded to provide basic TCP/IP transport layer
services, and WINROUTE runs as the top layer, providing the packet routing
function. The following is a sample batch file for loading all the required
software for the router:

AE2 IOBASE=340 IRQ=2
AILANBIO
NB_DRV -N:60
WD80X3 -I:3 -M:D800 -B:280 -N:61
ROUTETCP
WINROUTE

Important Note: In order for the router and the UNIX computer to communicate
properly, the address of the router must be added to the TCP/IP routing table on
the UNIX machine. Refer to Chapter 3, "Setting Up Routes," in the WIN/ROUTE
Installation and User Guide for specific instructions.


Installing and Running Pathway/Access:
The Pathway/Access installation diskettes contain both the network interface
drivers and the application programs (e.g. FTP, TELNET, etc.). The installation
process places the files in a directory named PATHWAY on the hard drive.
Additionally, it appends a line to the CONFIG.SYS file that loads the
PWTCP.SYS driver. This driver is similar to the WINTCP.SYS driver and
contains configuration information that is used by the Pathway kernel program,
PWTCP.EXE. As with the WINTCP.SYS driver, use the CUSTOM program to
customize the PWTCP.SYS information so it can be used by the kernel.
Variables such as the Internet address, host name, and username for a
particular PC are set using CUSTOM. Appropriate values and ranges for these
settings are documented in the Pathway/Access Installation Guide, but there are
some that must be set to specific values to ensure correct network operation.
These are:

1) The Default Gateway address must match the Internet address of the
LANtastic interface on the router. Set it using the "Set default
gateway's address" selection on the main CUSTOM menu.

2) Using the "Select program parameters" selection from the main
CUSTOM menu choose "Set expert parameters" on the Program
Customization menu. Set the number of "large packet buffers" to 10 and
their size to 512.

Reboot the PC once customization is complete to load the new values.

Figure 2 on page 2 shows the protocol stack for the PCs on the LANtastic
branch of the router. As it suggests, all of the LANtastic TSRs are loaded
before running any of the Pathway/Access programs. The LANtastic NOS TSRs may
be loaded into upper memory on machines with support for upper memory
functions, but the Pathway TSRs should be loaded in low DOS memory. After
loading the desired NOS programs, run the Pathway NB_DRV.EXE and
PWTCP.EXE programs. As with the router, the NB_DRV driver provides IP to
NetBIOS translation, and PWTCP is the support layer for TCP/IP applications.
The following batch file could be used to run both LANtastic and
Pathway/Access on a typical PC:

AEX IOBASE=340
AILANBIO
REDIR TEST LOGINS=10
NB_DRV
PWTCP

Once the above batch file has run, TCP/IP applications such as PING, FTP, and
TELNET can be used to access the IP network.


Compatibility Notes:
Artisoft has successfully tested the PING, FTP, FTPD, TELNET, RCP, RSH,
RLOGIN and LPR functions in the configuration outlined in the Test Equipment
Configuration section above. In addition, Pathway/Access includes a Windows
3.0-based program that includes FTP, TELNET and LPR services. We tested
this utility and also found it compatible with LANtastic and LANtastic for
Windows. Running FTPD in "background mode" (using the -b command line
switch) is not supported.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
