I also wanted to "harness" the power of my 48sx from my PC.  I found out
about the 'remote host' command from the net, but believed that there 
had to be an easier way.  Unfortunately, a call to HP confirmed that
you are supposed to use remote host.  

Well, I got tired of typing remote host, so I went out and bought
a program on the kermit protocol.  I now have a small program that
will talk back and forth to the hp48sx without the remote host 
command.  (It isn't pretty, but it is a start in the right direction.)
I haven't worked on it for a while, but I can make it available via
anonymous ftp if people would like it.  (I quit working on it when I
found out that I wouldn't be able to use a lot of the commands, ie
like EquationWriter from the PC.)

I also have a program that will display the hp48sx screen on a PC.
(ie a bit by bit copy).  Once again, not a finished program, but 
enough to prove concept.

I am currently working on a program that has the potential of being
very useful and need some information on how the Saturn processor
'talks' to the i/o chips in the 48sx.  Any help would be 
greatly appreciated.
