As Bill points out you need an A suffix to the proc name for that dll call. Any windows api call that has char arguments typically has a version with the A suffix for ascii (1 byte chars) or W for wide char. In most cases you will want the A version.
Not sure why you working with duplicate socket. I would think the normal J socket library would give you enough to get things done. I'm a bit tied up this week (conference in England) so my replies will be short and incomplete. My suggestion would be that you dig a bit more into what JHS has to offer and how it does it. You mention that the JHS console was locked. Keep in mind that normally that console task is running on the server and doesn't even have a terminal session. With JHS you have complete access to the J repl through the jijx browser app. In addition to the ide jijx interface you can create any javascript page you want that can use J as a repl (either in the J language or in a language designed especially for the app). Get familiar with jijx/jijs/file pages that are standard parts of JHS and then look at the demos for custom app examples.
