data sent on TcpClient.Connect

[aatif]

I am using a TcpClient to communicate with a remote system.

I need to ask is there any data or 'conenction string' that is implicitly sent on TcpClient.Conne ct function?

Because when I connect, the remote system admin sees some incoming data from my app.

Secondly, is there any alternate to send/receive ASCII data instead of TcpClient?

Thanks
