You're currently dumping out the raw bytes. Not very interesting, and
that's why it's not easy to read. I would recommend (a) decoding the
bytes to text, and (b) splitting it on "\r\n", thus getting it
line-by-line.

What you may want to consider, though, is using an actual IRC library.
It'll handle all kinds of details for you :)
