O.K.  you can set the serial port with setscc to be a full 8 bits wide.
The data will get through, EXCEPT CERTAIN control code, ^D ^S ^Q ^T ^C
Currently, Adobe in it's infinite wisdon
has not seen fit to tell us how to get around this problem.. I seem to
get stonewalled by them anytime I reqest info on this.  Perhaps you would
be better off going paralell, but for some perverse reason, these above
control characters still won't go through.  In addition, PS uses
the "cooked" mode, that is 0x0a 0x0d  gets converted to 0x0a.  This can also
screw you up.

Cheers
