OPEN PORT

The OPEN PORT instruction allows you to open a port previously created with the CREATE PORT command. This command accepts, as a parameter, the string with the unique and printable identification code of the port, equivalent to an 8-digit hexadecimal code. The result of the call will be the same identifier, which can be used for other instructions. The instruction will issue an error if the port is unknown. In case the provided port is an empty string, this command will behave like CREATE PORT.
