I suppose you're connecting to busybox based on your shell prompt?

here i want to connect remote telnet server.

Use appropriate shell prompt. The one you get when manually connecting via linux/windows.

@Kaimunchi - This is not a paid service. You leverage this library to make it work for you. People don't just help everyone here for free. I invested at least two years of my precious time to provide you with this library for free, so the least you can do is try looking into what might be the issue on your side and also provide bugfixes if they arise. Thank you.
