Dear experts,

I might be showing my ignorance, but surely there must be a piece of software
around that enables simple X-window applications (like dxmail or dxterm) to run
extremely fast remotely via a modem.

My experience is that to run X-applications remotely via a modem is EXTREMELY
slow. For example, I find that it takes 20 seconds just to throw up a dxterm
window when I use DEC's Excursion software on an Alpha XL 266 (windows NT) 
connected to an Alpha 3000-600 (running DecUnix) with a 28,800 bps modem.
DXmail is even worse, taking about 40 sec to appear. This seems to me ridiculous
when running such standard DEC X-windows on two DEC machines. Surely one does 
not need to send every single pixel of a dxmail window down a modem line. If the
local machine knew what a dxmail window looks like, it would only need to 
receive simple ASCII text to produce a local copy of the remote dxmail window,
and it should be able to do that in a fraction of a second!

Am I dreaming, or is there indeed a software product that is intelligent enough 
to know about standard window formats like dxterm and dxmail?

Thanks in advance,
