I am looking for hard-core information on how to write simple routines
to write and receive characters from a Super Serial Card using an
interrupt-driven handler. This is, of course, for a modem program.
I have found various sources of information lacking in depth for what I
need. I already have the SSC reference manual (the old one), the IIe
technical reference (which describes firmware almost exclusively), and I
also have a few sources on interrupts under ProDOS.
Please mail to me, or post here. Of particular interest to me is how the
CONTROL, STATUS, and COMMAND registers on the SSC are used in conjunction with
interrupts to get incoming characters, and conversely, to send them out.
Thanks.
