Help I'm stuck!

I need to talk to a piece of kit that uses UDP to accept binary commands and send back replies. One UDP packet sent to the unit will result in one reply packet sent back to the IP/port that it came from.

I'm trying to create a set of packages/objects to communicate with the unit. The main object I've created is the session object. When I create an instance of session I want it to send a login command and receive the reply and then have a thread that will receive and process each reply as it comes until the session is destroyed.

My problem is sharing the socket connection between the session object (to send commands) and the thread it creates (to recv replies).

I've tried two approaches which both fail:

• Firstly, storing the IO::Socket::INET object in a shared variable. This doesn't work because I can't store typglobs in a shared variable.
• Secondly, creating a second IO::Socket::INET within the thread. This doesn't work because it opens a new local port which doesn't receive the replies because they go back to the original port that the command came from. I've even tried setting the LocalPort of the thread's socket to the same port as the original socket but it fails because it's already in use.

I've run out of ideas of how to get this to work. Anybody know of another way to do this? I'm using ActiveState 5.8 in WinXP

Thanks!
