[comp.sys.atari.8bit] Atari 850 help

phil@calvin.EE.CORNELL.EDU (Phil Erickson) (02/18/89)

I'm in the process of building an 850 interface lookalike, but I need
to know the various commands that an applications program would send to
the 850 handler  (i.e.
   XIO 34,0,etc.)
and their meanings (as in what bit in the aux bytes sets what).  Not having
access to someone who owns an 850 manual, all I know is what I can glean
from the source code for some terminal emulators.
I want to write a handler for my interface that is identical to the 850's
from a terminal emulator's point of view, for compatibility reasons;
thus, the desire for a list of all the valid 850 commands and the 
meaning of the AUX bytes associated with them.

If anyone on the net has an 850 manual lying around and could e-mail me
the codes located in there (under "programming info", I suppose), I would
be very grateful.

Thanks in advance,
