The SetConnectionByName method uses the connection name to set the connection for a newly created autECLXfer object. In Z and I Emulator for Windows this connection name is the short ID (character A-Z or a-z). There can be only one Z and I Emulator for Windows connection open with a given name. For example, there can be only one connection “A” open at a time.
Note: Do not call this if using the autECLXfer object in autECLSession.
