Detailed Description

Represents a BAOS IP4 device with an underlying TCP connection (with BAOS unsecure connection-oriented)

The connection information like ip address and the port can either be set in the constructor or later with setConnectionData. This has to be done before opening a the connection to the device.

This connection type is supported by BAOS 771 BAOS 772 BAOS 773 BAOS 774 BAOS 777 BAOS 774.1 when configured as auto-connect BAOS 777.1 when configured as auto-connect
