To communicate on a network a machine must have a valid IP address
and some configuration settings. Most modern computers and devices
today use DHCP (Dynamic Host Configuration Protocol) to get their IP
address automatically from a router on
the local network. mTCP includes a DHCP client that allows your PC
running DOS to get an IP address using DHCP.
The mTCP DHCP client is very simple - its only job is to talk to a DHCP server and get an IP address for your machine. It has been tested with a wide variety of DHCP servers and routers.
Below is a screen shot of DHCP running:
The mTCP DHCP program requires that some setup be done before you
can use it. Please see the mTCP documentation for how to do that setup.
If you do not have a router or DHCP server on your network you can
always configure the IP address and network settings by hand. Before
DHCP most machines were configured that way but now DHCP is far more
common. The mTCP documentation has instructions for performing static
DHCP is included with the other mTCP based applications. They can be downloaded from the main mTCP page here.
