I've not the foggiest idea what serially bi-directional could mean. AFAIK ...

Try it.

  1. Connect a socket to a server that attaches, and then tries to read from the client.
  2. Start a thread (in the client) that goes in to a read state on that handle.
  3. Then try to write something to the server via that handle from the main thread.

The write will block indefinitely pending the completion of the read in the thread, which will never occur because the server won't send anything.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
