Great article, but it still does not work for me. Can you help?

$ socat ./serial1 tcp4-listen:9988
(it just waits)
(in another shell)
$ telnet 127.0.0.1 9988
rying 127.0.0.1…
Connected to 127.0.0.1.
Escape character is ‘^]’.
Connection closed by foreign host.

$ socat UNIX-CONNECT:./serial1 tcp4-listen:9988
2008/09/18 15:09:06 socat[4499] E connect(3, AF=1 “./serial1″, 11): Connection refused

$ socat UNIX-LISTEN:./serial1 tcp4-listen:9988
2008/09/18 15:22:37 socat[5518] E bind(3, {AF=1 “./serial1″}, 11): Address already in use

and I have no idea how to “disconnect” it.

The socat manual is long but it is not clear how to. Also it says that it won’t accept the 2nd connection. So does it mean this behaviour???

Thanks,
Yoichi
