Forget about "telnet". It's a normal tcp socket connection. I'm
confident that VB6 can do that. Did you look at the examples as
I told you? The c/c++ examples in scripts/example/ don't even
mention "telnet".

Melchoir, just looked up MSDN, I quote;
"Using the Winsock Control
A WinSock control allows you to connect to a remote machine and exchange
data using either the User Datagram Protocol (UDP) or the Transmission
Control Protocol (TCP). Both protocols can be used to create client and
server applications. Like the Timer control, the WinSock control doesn't
have a visible interface at run time.
Possible Uses
Create a client application that collects user information before sending it
to a central server.
Create a server application that functions as a central collection point for
data from several users.
Create a "chat" application.
Selecting a Protocol
When using the WinSock control, the first consideration is whether to use
the TCP or the UDP protocol. The major difference between the two lies in
their connection state:
The TCP protocol control is a connection-based protocol, and is analogous to
a telephone the user must establish a connection before proceeding.
The UDP protocol is a connectionless protocol, and the transaction between
two computers is like passing a note: a message is sent from one computer to
another, but there is no explicit connection between the two. Additionally,
the maximum data size of individual sends is determined by the network.
The nature of the application you are creating will generally determine
which protocol you select. Here are a few questions that may help you select
the appropriate protocol:
Will the application require acknowledgment from the server or client when
data is sent or received? If so, the TCP protocol requires an explicit
connection before sending or receiving data.
Will the data be extremely large (such as image or sound files)? Once a
connection has been made, the TCP protocol maintains the connection and
ensures the integrity of the data. This connection, however, uses more
computing resources, making it more "expensive."
Will the data be sent intermittently, or in one session? For example, if you
are creating an application that notifies specific computers when certain
tasks have completed, the UDP protocol may be more appropriate. The UDP
protocol is also more suited for sending small amounts of data. "
