Subject: Telnet question

I'll ask the questions first, and then show the code and examples
below:

waitfor is timing the script out. Is it because it isn't recognizing
that password input is complete? or is it because the device doesn't
issue a command prompt after the password is input? (The user has to
hit the Enter key to get the command prompt)?

I've interjected comments on the behavior of the script with <ROLFE-...
below.

I'm running the following script to log on to a peice of hardware:

   require 'net/telnet'

   tn = Net::Telnet.new('Host'       => '192.168.47.150')     { |str|
print str }
   tn.login("myusername", "mypassword")  { |str| print str }

This is how script displays in FreeRIDE:

    >ruby c:/Documents and Settings/rdlugyhegwer/sampler.rb
    Trying 192.168.47.150...
    Connected to 192.168.47.150.
    WELCOME TO SYMMETRICOM NETWORK INTERFACE!
    USER NAME: myusername

<ROLFE-It pauses here for a little while, and then continues with:>

    PASSWORD: mypassword
    NETWORK INTERFACE 192-8001      (c) 1998 - 2006 SYMMETRICOM
    ALL RIGHTS RESERVED
    LOGIN SUCCESSFUL!

    c:/ruby/lib/ruby/1.8/net/telnet.rb:551:in `waitfor': timed out
while waiting for more data (Timeout::Error)
	from c:/ruby/lib/ruby/1.8/net/telnet.rb:678:in `cmd'
	from c:/ruby/lib/ruby/1.8/net/telnet.rb:725:in `login'
	from c:/Documents and Settings/rdlugyhegwer/sampler.rb:4
    >exit


If I log in using a terminal program, it looks like this:

    WELCOME TO SYMMETRICOM NETWORK INTERFACE!
    USER NAME: myusername
    PASSWORD: *****
    NETWORK INTERFACE 192-8001      (c) 1998 - 2006 SYMMETRICOM
    ALL RIGHTS RESERVED
    LOGIN SUCCESSFUL!

<ROLFE - the user must hit the ENTER key on this blank line to get the
command prompt>
    >quit

    GOODBYE.

Any suggestions? I've read a lot of the documentation online and tried
variations on the telnet.rb sourcecode. Your help would be very much
appreciated...
