Thanks Rick for your help. I wanted to use server push because the server is receiving strings from the modem and I didn't want to risk overloading data if the client is not fast enough to retrieve it.

If the server called a method of the client, passing the received string has a parameter, instead of assigning the string to the client property, would that have worked?

TIA
