I've never looked so I'm asking the astonishing question, "You mean
there are no USB to serial port cable drivers that look like standard
serial ports to Linux?" Um, maybe someday someone will get motivated
to do this. It is something likely to be very urgently needed in the
future. (I suspect all the adapters use the same small number of
chips which perform this function. So it should not be TOO bad.)
