We have a customer which has a medical devices that has message displayed on it. they can get us these mesages. we need to update the sql server with that. for Patients records. Language and method to do this is really open. since i only know C# i am posting that but there is better way of course we can. We need to use the ecov-110 you can see the manual here: <[login to view URL]> *** IMPORTANT UPDATE MORE SPECS NOW THANK YOU FOR YOUR PATIENCE ******* Need to create a Listener Service. The Service monitors the network for message coming from the device. Each device is connected serial to a box that moves the output through the Ethernet network. Need to know how to configure the system to sent the messages from the device to a specific Port address on the Server. All messages are queued and will contain the addresses of the sending devices. This is how we can determine from which device the message orginated.
