Last week I asked for help on finding both a packet driver
that would recognize the WD8003W card (10BaseT) and some TCP/IP
software that would support the packet driver.
With a lot of help from the net, and particularly Ernie
Ellenberger and RL "Bob" Morgan, I am now telnet-ing and ftp-ing quite
happily between a PC (w/ 10BaseT card) and a SPARCserver 4/330 over
unshielded twisted pair. Since others seem to be asking about packet
drivers and the WD 10BaseT card, I thought I'd summarize the path I
took.
WARNING! I am anything BUT an expert on this stuff. It just so
happens that with a lot of assistance I was finally able to get it to
work. Hopefully the following notes will save others some time but
please don't expect me to be able to answer many questions.
(1) Packet drivers can be obtained via anonymous ftp from
sun.soe.clarkson.edu. The file you want is
/pub/packet-drivers/drivers.arc
This is an MS-DOS archive file and to unpack it on your DOS machine
you'll need to download the file
/pub/packet-drivers/arce.com
(Be sure to use binary mode when ftp-ing and also when downloading to
your PC whenever appropriate.)
(2) On your DOS machine, unpack the drivers with the command
C:\> arce drivers.arc
(3) Look among the unpacked files for one called WD8003E.COM. This
packet driver apparently works with the whole WD8003 family of cards.
I know for sure it works with the WD8003W (10BaseT card).
(4) If you use the default settings on the WD8003W card, you load the
packet driver on your DOS machine with the command
C:\> WD8003E 0x60 3 0x280 0xd000
The arguments must be changed if you use different setup parameters.
Look at the DRIVERS.DOC file in the list of files that were unpacked
for further details.
NOTE: If the packet driver is loaded successfully, the harware
ethernet address of the installed card will be displayed on the
screen.
(5) To test out the packet driver, you will need network software that
supports it (surprise!). In particular, NCSA Telnet Version 2.2
obtained from 128.174.20.50 will NOT work. You need version 2.2D
available from omnigate.clarkson.edu. You will find both the telnet
and ftp program in a file called
/pub/ncsa2.2tn/ncsabin.tar
Ignore the note about untarring the file with special DOS-based
software. I untarred the file (after using binary ftp to my UNIX box)
with the standard UNIX tar command. I then downloaded telbin.exe and
ftpbin.exe using Kermit in binary mode and the programs ran fine.
(6) It is important to download the sample CONFIG.TEL file and to
customize it to reflect your set up. Below is the configuration file
I use on a "network" consisting of only two machines, the PC (IP#
36.110.0.12) and the SPARCstation (hostname casbs, IP# 36.110.0.10)
You may want to start off simple and add features gradually.
Example CONFIG.TEL file for a two-node network:

(7) After you have loaded the packet driver and have customized your
own version of the CONFIG.TEL file, run telnet with the command
C:\> telbin -h config.tel remote_hostname
or get ftp going with
C:\> ftpbin -h config.tel remote_hostname
(8) If you run telbin, type ALT-h to view a summary of your options.
Hope this helps!
