13: =head1 SYNOPSIS
14:
15: use Net::Telnet::Trango;
16: my $t = new Net::Telnet::Trango ( Timeout => 5 );
17:
18: $t->open( Host => $fox ) or die "Error connecting: $!";
19:
20: $t->login('password') or die "Couldn't log in: $!";
21:
22: # Do whatever

24: $t->exit;
25: $t->close;
26:
27: =head1 DESCRIPTION
28:
29: Perl access to the telnet interface on Trango Foxes, SUs and APs.
30:
1.20 andrew 31: Another handy feature is that it will parse the output from certain
32: commands that is in the format "[key1] value1 [key2] value2" and put
33: those in a hashref that is returned. This makes using the output from
34: things like sysinfo very easy to do.

51: =item new
52:
53: Same as new from L<Net::Telnet> but has defaults for the trango 'Prompt'
54:
55: It also takes an optional parameter 'Decode'. If not defined it
56: defaults to 1, if it is set to 0, it will not decode the output and
57: instead return an array of the lines that were returned from the
58: command.
