Could it be that if it failed to open there is nothing to close? A quick look at io::Socket leads to io::handle where they say: undef $io; # automatically closes the file if it's open Well It's better than the Abottoire, but Yorkshire!	[reply]

`$call = ... or $inactive = 1;` makes $call = 1 if the port is down. Then you have "close 1;" later. This might be the problem.	[reply] [d/l]
