hi ramesh,

 you got to send your data using the telnet protocol. Since you are
connecting to the telnet server on the host, you will have to send your
data in a format which it understands. Since when ever a telnet client
connects to a telnet server a lot of data gets transferred between the
two ( which is invisible to you ) which is essential for establishing a
session, you got to pass the session info too.
