How can I embed a telnet session into my app?

Hi,

I have now published my first app on market:

https://www.nextpit.com/en/android/forum/thread/401068/Chess-for-All-LITE-My-first-Android-Application

The next feature I am trying to install is a connection to a chess server.
The Free Internet Chess Server (FICS) offers a connection with telnet.
I was trying that with a simple Command Promt window on my PC:
