I have an interest in this myself, and hope soon to be acting on it.
Meanwhile, MY prime resource is this:

On page 776 of the <Ruby Cookbook> (see "Resources" below) takes up
"Getting Input One Character at a Time". It discusses the Curses
extension that is a part of Ruby, and the Highline library (a gem). It's
only a couple of pages, but its the most focused discussion I've seen
yet. I assume that I'll learn more from the RDoc material associated
with the Highline gem, and probably in various blogs out there
somewhere, etc.

All I know... hope it helps.

Resources:

* O'Reilly publisher sales page:
http://oreilly.com/catalog/9780596523695/ - Prices here seem high. I
know I didn't pay $40 for my PDF version. Amazon may have used copies
for cheaper.

Here's a blog post you might enjoy, though it won't help with the
TCPServer case being discussed in this thread:

James, THANKS! That pretty much nails it. A fine contribution to the
community. (Nice clean minimalist blog layout too...) ~t.

To be clear, is this a tcpserver running on the local system where you
want to catch the signal (CTRL-X) or do you mean the tcpserver is
running on a remote system and you want to capture the local singal and
send that to the remote service?

Highline is an excellent example of a ruby library that takes a
single, hard problem and solves it really, really well.

Tim i need to catch the signal ctrl-x on local machine, to shutdown the
server.

The problem is this code :

client = server.accept
The signal ctrl-x does nothing.

Sorry if I wasn't clear, is the server local to the same machine where
you have the keyboard connected that will send the command? Will this
perhaps be on a remote (or local) server in shell/cli? That is, what
interface will you need to use to pass this signal to? (I hope that
makes sense).
