Can't interrupt/terminate Ruby script with Ctrl+C on Windows

My script opens TCP connection and reads data from server. If server does not respond I try to interrupt the script with Ctrl+C, but it does not work. The only way to terminate the script is to kill process in task man开发者_如何学编程ager. Any ideas how to interrupt such script?

require 'socket'

host = '...'
port = ...

s = TCPSocket.open(host, port)

while line = s.gets
  puts line.chop
end

s.close 

---

trap("SIGINT") { clean up; exit}

I noticed, that it I cick Ctrl+C while waiting response from server, and some time latter response comes, the application terminates. But while I wait on socket (s.gets), the Ctrl+C has no effect.

So I solved the problem by running network code in a different thread.

require 'socket'

host = '...'
port = ...

t = Thread.new do
  s = TCPSocket.open(host, port)

  while line = s.gets
    puts line.chop
  end

  s.close 
end

STDIN.getc

Now I can terminate script by typing any character. But still would be nice to know about alternative solution.

On Windows, type Ctrl+Pause
