These values must correspond to the type of connection between the control video device

port
The value of port specifies the serial port number for RS-232 and RS-422 connections. For
example, to specify that the device is connected to port 2 (sometimes referred to as
ttyd2), specify just the numeral 2. For TCP connections, port specifies the TCP port
number.
