Hi Ken,
If you know a port is open on a machine you can assume it is doen if you
cannot connect, you dont need any response beyond that a connection is
possible.
maybe these will help
>> either error? try[port: open/no-wait tcp://rebol.com:80]
["ahrgg"][close port "ping!"]
== "ping!"
(with a bad/closed port number)
>> either error? try[port: open/no-wait tcp://rebol.com:0]
["ahrgg"][close port "ping!"]
== "ahrgg"
>> either error? try[port: open/no-wait tcp://whatever.com:80]
["ahggg"][close port "ping!"]
== "ahggg"
>> either error? try[port: open/no-wait tcp://www.whatever.com:80]
["ahggg"][close port "ping!"]
== "ping!"
