	It sounds like what you really want to do is subclass 
Net::Telnet. That way you could say things like:

my $t = new Net::Telnet::Subclass( 'host', 10, 'password', 'secret' );
$t->change_password( 'newpassword','verysecret ');
# etc., etc.

	That would be the object-oriented way to do things, anyway. It 
might also help you find your bug, since it's highly likely that 
you'd trigger an error earlier and closer in the code to the actual

	It should work as you described it, which probably means there's 
a bug in your code. I'd walk through this code in the perl debugger 
and make sure that you are getting a object back from your call to 
Net::Telnet and that that object is being correctly passed along to 
the other functions you've defined.
