While the top level concept caught my interest, I can provide no feedback due to a couple of things that you may be able to help with:

• Please provide a short working code example that demonstrates your issue. Include it in <code>...</code> tags for readability. This allows those interested in assisting the opportunity to execute the example to try to reproduce and help diagnose your issue.
• Provide the output that you _do_ see, again, enclosed in <code>...</code> tags. How do you determine that the keystroke is not sent? Perhaps the response is being swallowed by the code. Perhaps the terminal emulation for the connection is not configured properly. Personally, I would guess that the issue has to do with buffering, but that is just a guess (see point one above).

Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.

Read Where should I post X? if you're not absolutely sure you're posting in the right place.
