Wow. This *is* hard yakka.

if select([@sock], [], [], 0.1)
  @sock.recv()
  etc, etc.

Your program is asking the "recv" block to be called if select()
returns true.

We have established the following:

(a) select() returns nil or anArray (from a RTFM).
(b) nil != true (axiom).
(c) anArray != true. (See your irb snippet above).

Thus you are requesting the block never to be called. Your program is
working perfectly, and the socket is brimming with bytes :)

Try this (and pardon my ruby, I've forgotten most of the syntax):

while true
  sockArr = select([@sock], [], [], 0.1)
  if !sockArr.nil? and sockArr.at(0).include?(@sock)
    @sock.recv(256)
    etc, etc.

Pardon my didactic tone too. I hope this helps.

Yours

Chris
