i'm not that familiar with serial port settings either, but IIRC the cflag is
used to set the requested byte size of the transferred chars (cf
http://en.wikipedia.org/wiki/Serial_port#Data_Bits). Thus, according to the
above CS8 is used for setting up transfer of any kind of data over the serial
connection.

err, you mean keyspan_open() ...
..and yes, almost all of the usb to serial converter drivers call their own
*_set_termios-routine so that they could "synchronize" the line discipline user
settings with those of the converter.
