No.  telnet simply establishes a tcp connection on that port.  So for 
example, to 'manually' pull a page from a webserver you can do:

telnet www.example.com 80

and then when the prompt returns issue an HTTP request manually a la:

GET / HTTP/1.0

In this case, telnet'ing to the port that your server is supposedly 
binding to will establish whether or not anything is bound to the 
specified port.  You should also run 'netstat -an | grep LISTEN' on 
your server and look for the port number that you are trying to bind

I think you need to figure out what the problem is first.  Is the 
server not binding?  Is it firewalled off, etc.
