Hello Monks,

I should write a thin and easy emulation of a networked device which is controlled by simple UDP commands. The device listens to UDP port 7070 and if a request arrives, it immediately responses with some status data.

I solved this easily with 
use IO::Socket;
my $PORTNO = 7090;
$sock = IO::Socket::INET->new(LocalPort => $PORTNO, Proto => 'udp')
while ($sock->recv($request, $MAXLEN)) {
    $response=parseRequest($request);
    $sock->send($response);
}

My problem is, that this box should also send time-triggered status notifications every five seconds. Additionaly, these "five seconds" and the content of the status notifications are modified by the incoming request.

Currently, I have no clear idea, how the solution might look like. Any hint?

Thanks for your time!
