10:
11: Net::Telnet::Trango - Perl extension for accessing the Trango telnet interface
12:
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
23:
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:
31: Another handy feature is that it will parse the output from certain commands that is in the format "[key1] value1 [key2] value2" and put those in a hashref that is returned. This makes using the output from things like sysinfo very easy to do.

49:
50: Same as new from L<Net::Telnet> but has defaults for the trango 'Prompt'
51:
52: It also takes an optional parameter 'Decode'. If not defined it
53: defaults to 1, if it is set to 0, it will not decode the output and
54: instead return an array of the lines that were returned from the
55: command.

1026:
1027: There are still a lot of commands that are not accessed directly. If you call them (as cmd("command + args") or whatever) and it works, please send me examples that work and I will try to get it incorporated into the next version of the script.
1028:
1029: I also want to be able to parse the different types of output from commands like su, sudb all and anything else that would be better available as a perl datastructure.
