Hello,
I am looking at a code fragment that I dont understand properly.

crash out - cannot go on

I'm assuming that the "errmode" is "return." When the second $telnet->waitfor() succeeds, the method will return a list containing values for $prematch and $match. If that happens, it means that the host is demanding a new password, and since the script can't handle that, it exits. The "if" statement tests whether a non-empty list was returned by $telnet->waitfor().
