Hello Booth,

Not quite true.  There are many things that can be done to the display once it 
has been 
received at the PC.

Take a look at NewLook <http://www.looksoftware.com> and see what can be done 
over and above 
what is in the data stream.  NewLook connects using the Telnet server (or 
Passthrough server 
for SNA) and can do some quite amazing things.  It's windoze only which annoys 
me but that's 
not my decision.  You can download a 30 day trial.

Disclaimer:  I am writing the server component for Look Software so I do have 
an interest in 
the product.

Regards,
Simon Coulter.
