iug:

If it's stuck on the cmd line, I'd expect that the command is waiting for additional input or something similar. Have you read the "Debugging" section of Net::Telnet? It describes a couple functions (input_log() and dump_log()) that you can use to see what's happening so you can figure out the situation. As you've presented it, we don't know what "command" is, what it's doing or why it's hanging.
