# I launch socat as
# % socat TCP-LISTEN:4161,fork,reuseaddr FILE:/dev/ttyUSB0,b57600,raw and what
# I immediately get is a TCP server listening onto port 4161 and ready to relay
# any incoming connection to the /dev/ttyUSB0 serial port with a 57600 baud
# rate. And not only do I have no more concern about accessing the serial port
# properly, but also I can access a port located on a remote computer as easily
# by launching socat there instead of locally.
