You seem to be doing OK, but ask yourself how you would *know* about the
response, when nothing in your code actually reads the socket to see what's
coming back?

In the general case you need to be able to recognise the end of a response,
and I don't know enough about IRC to help you with that, but try scattering
the odd recv() call in your code to see whether the host is sending
responses. The fact that you aren't seeing error messages is at least
encouraging!
