 Perl access to the telnet interface on Trango Foxes, SUs and APs.  
   Perl access to the telnet interface on Trango Foxes, SUs and APs.
 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.
