I know there must be a way to do this, since an Apple II can be used from
remote by doing a pr#2 and in#2 at the same time.  I just need to know
the locations to peek and poke too.  I can live with the pr#2, but you can't
use the in#2 and the get command for my purpose, it stops the whole program.

This is just one of the things I wanted to work on, does anyone have the
source code (or partial source code for DDial, I just need to see the hardware
routines...).

I'm going to attempt to write a 2 line BBS, simple, but a little more
complex that DDial (chatting and true message bases).  If someone could
write me a couple machine language routines for the Apple II, it would
be greatly appreciated.  Although, I don't know how far I will get.  I 
don't know much about the Apple II.  The Commodore 64 was my machine, I knew
all the tricks for that machine.  Apple seems to keep the general public
blinded.  (or maybe its because I'm a late comer to the II world.).
