Telnet ip address at a given port

Question

What's the difference between:

C:>telnet somehost 25

and

C:>telnet
Microsoft Telnet>open somehost 25

Why in the first case I immediately get a new completely black prompt, while the second case remain freezing to:

Connecting to host...

Help me.

Answer 1

There is no difference. Try telnet /? and the help command from inside telnet.

What you can see on the screen in the second case is just because launching a command from the telnet prompt has more verbosity.
