For us it is more important to know the protocol that this device

This should be @socket.write "SEND\r\n".

If your line terminator is "\r\n" then you probably also want to use
TERM = "\r\n".freeze
while line = @socket.gets TERM

I'd start by creating a handler class per connection. This could look
like this:
require 'socket'
class DeviceHandler
TERM = "\r\n".freeze
def initialize(socket)
@socket = socket
@thread = Thread.new do
@socket.each_line TERM do |line|
data = parse(line)
end
end
end
# more methods...
private
def send(...)
@socket.write(... + TERM)
end
end
server = TCPServer.open(3012)
handlers = []
while (client = server.accept)
handlers << DeviceHandler.new(client)
end
But how this is really set up (and especially if you need to start a
thread in the constructor) hugely depends on the protocol spoken by
the device and what you want to do with it.
Cheers
robert
