I'm trying to use the telnet library. I don't know Ruby AT ALL
(evaluating it side by side with Python to see which is going to be best
for my admin chores; this is my very first script), and this has got me
stumped:

   require 'net/telnet'
   t = Net::Telnet::new(
      'Host'       => 'somehost.com',
      'Prompt'     => /:.*>/,
   )
   out = lambda do |c| print c end
   t.login('someusername', 'somepassword', &out)
   t.cmd('dir', &out)
   t.cmd('dir', &out)

The second dir command hangs with the server responding "More?" Here's
the tail end of the output log, after the first dir command:

   ...
   04/13/2011  04:21 PM    <DIR>          Searches
   04/13/2011  04:21 PM    <DIR>          Videos
   04/16/2011  12:54 AM             6,558 _viminfo
                  1 File(s)          6,558 bytes
                 13 Dir(s)  279,022,981,120 bytes free

   C:\Users\foo>dir
   More?

And it just hangs there.

Full logs here (names changed to protect the innocent):

This is a bitch to Google ("?" is ignored), but I found someone else
asking the same question on Stackoverflow, but he got no response
(http://stackoverflow.com/questions/3450942/ruby-telnet-lib-weird-response).
You guys could help both of us out. :)

------------------------------------------------------------------

In a slightly unrelated question, I don't understand why I have to do
this:

   out = lambda do |c| print c end
   t.login('someusername', 'somepassword', &out)
   t.cmd('dir', &out)
   t.cmd('dir', &out)

Rather than simply this:

   t.login('someusername', 'somepassword', &print)
   t.cmd('dir', &print)
   t.cmd('dir', &print)

Seems kinda pointless to make a function which does nothing but pass
it's arguments unaltered to another function.
