10.2 DOS TCP/IP configuration – Packet Driver and WATTCP
A standard packet driver for DOS is installed on the board as shipped, along with sample network
applications written with the public domain Waterloo TCP/IP software (WATTCP). WATTCP is a freely
available package (including source code) that provides TCP/IP connectivity for programs written for the
DOS environment. See the Technologic Systems download page
http://www.embeddedx86.com/downloads/wat2001t.zip
In addition, we have written a simple DOS HTTP web server using WATTCP that is included on the TS-
5500 utility disk. The simple web server uses CGI calls to control a DIO pin from a web browser. Full
source code is included, and you are free to modify and extend the code for your own use on
Technologic Systems Single Board Computers.
The DOS packet driver (DM9PCIPD.COM) is loaded by
AUTOEXEC.BAT
once DOS starts. Hardware
settings are read from the EEPROM chips and used by the packet driver to initialize each DM9102A.
Below is an example of the DOS command line to load a packet driver for the Ethernet interface:
DM9PCIPD 0X60
The TCP/IP settings for the WATTCP code are stored in the WATTCP.CFG configuration file in the
A:\ETHERNET directory, this file must be modified for the network environment where the TS-5500 will
be installed.
10.3 WATTCP.CFG configuration file
my_ip=192.168.0.20
// IP address of this Ethernet interface.
hostname="epc.embeddedx86.com" // Host name of this computer.
netmask=255.255.255.0
// Used to determine which IP’s are local.
gateway=192.168.0.1
// Gateway for internet access.
nameserver=192.168.0.1
// Name server for domain name lookups
.
With the WATTCP.CFG file properly setup and the 10/100 base-T cable connected, you should be able
to ping other nodes on the network, i.e. ‘
ping www.embeddedx86.com’
Other WATTCP examples include: serial to telnet redirector, http file download, telnet server, and finger,
web server with I/O control. Many more can be downloaded from the internet as freeware.
10.4 DOS TCP/IP configuration – MS Client for DOS
The Davicom Ethernet adapter has the MS Client for DOS driver available. This has been tested and
found to work on Windows workgroups as well as Samba workgroups. Check the Technologic Systems
web page for driver downloads (
www.embeddedx86.com
).
