I'm not really sure what you're saying here.  Are you saying:

1.  You're not connected, and you issue a telnet command.
2.  PPP starts to dial, but it doesn't connect, and you have to kill
    it.

Or are you saying:

1.  You have an idle telnet connection, and the line isn't connected.
2.  You enter something, which causes PPP to dial, but you don't get a
    TCP-level connection.

The second scenario is typical for dynamic addressing.  The first I
don't understand, but it might not be the case.

If it's (2), the answer is "get a static address".

Can't you do this from telnet to port 3000?  But I can't see why you
would want to.
