Multiple Connections

We are currently using the Connect ME product. We are noticing undesirable results when more than one user tries to use the tcp server for serial communication. The first user connects and gets the serial resource. Everything works wonderfully from that point. However, when a second user connects the socket connection is made but there is no notification that another user is currently using the serial device. From the end user’s standpoint it looks as if the device is not working any longer. Personally I don’t think this is appropriate behavior. Could someone please comment on this behavior?
