Yeah. RS232C can operate in many different ways, using the various "wires" differently. Opening a serial port is just the beginning of the work; then there is deciding what signals and handshake to use. Oh....the good ol' days.
There's never time to do it rite, but there's always time to do it over.

That's not a bug: a daemon can then open a port and detect whenever you
plug something and switch it on.
