allow to define default settings on the IO class:
- a default 'port' may be given for tcp
- defaults like 'baudrate' or 'parity' might be given
for serial connections
this avoids explicit settings in the config file in case
the settings can not be changed or have a typical value
other than the defaults in serial.Serial
