The value of INFMSG_mask<x> below are that each bit represents one of the INF class
messages (Bit 0 for ERROR, Bit 1 for WARNING and so on.). For a complete list, please see
the Message Class INF. Several configurations can be concatenated to one input message.
In this case the payload length can be a multiple of the normal length. Output messages
from the module contain only one configuration unit. Please note that I/O Targets 0, 1 and
2 correspond to serial ports 0, 1 and 2. I/O target 3 is reserved for future use.
