[comp.sys.mac.programmer] serial device driver reference sources wanted

ross@cattell.psych.upenn.edu (Ross Porter) (10/20/90)

I have a peripheral device to connect via the serial port.
The suggestion is that I use a device driver layered on top of the
standard serial device driver.

I'm looking for information that goes beyond the simple factual
information found in the Inside Macintosh series.  Books, example source
code.
