How can i telnet to port

[Drogbaa]

Hi,
I am trying to use telnet with using a specific port. I am having problems sending over SMTP. I dont have any idea about it. Can anyone help me with telnet for specific port?

To telnet to an SMTP server named smtp.comcast.net, for example, from a Windows machine, at a command line type (without the quotes)

"telnet smtp.comcast.net smtp" or "telnet smtp.comcast.net 25"

If you get something like

"220 OMTA03.westchester.pa.mail.comcast.net comcast ESMTP server ready"

you're connected. Otherwise you'll get some explanation of why not.

For a list of commands, see http://www.freesoft.org/CIE/RFC/821/15.htm.

Telnet is a network protocol used to provide a bidirectional interactive communications facility. Telnet provides access to a command-line interface on a remote host via a virtual terminal connection. It predates TCP/IP. It runs over NCP protocols.

Telnet is built-in in windows. It is situated in C:\WINDOWS> telnet univax.host.com You can start ir by double-clicking on the Windows icon. You can also use he following cmd command prompt: telnet hostname or simply telnet. It requires host name to get telnet window. Then it will allow you to connect it.
