This is just a little note ... Use of the 'type' parameter in the device driver
on a GIMIX system running OS9 allows the setting of # of data bits , # of stop
bits, parity and to a certain extent baud rate (division of baud rate
generator) when using a 6850 acia 2-port serial card. I'm not sure as to what
extent this can be used on a RS CC.
