Dear Colleague,

     At the workshop of representatives from  the European academic 
networking communities held on the 13th to the 15th may 1985, it was
decided to take a number of  initiatives to  foster inter-networking 
in  Europe.   One of these  initiations  was to  enable 'Full Screen 
Services' and  I have been asked to follow this up.

     I  am  writing  to  you  as  a named  'representative' of  your 
country/organisation to seek your views on the current position  and  
how it can  be progressed.  I am  including a full circulation  list   
with this letter and would  request that  you send  your response to 
all the people on the list to promote a genuine dialogue.

     There  are a number of problems  associated with handling  full
screen facilities across a  network.  The solution to these problems
is  not immediately  obvious  and there are advantages in attempting
to avoid major duplication in effort.

     To  what extent do  you support full  screen  terminal services  
across networks?

     Triple-X (X3, X28 and X29) can  be used to support  full screen
working  although  it  can  be  difficult  to sustain  a  reasonable 
performance.

     Is it used by you in this way?  What  alternatives, if  any, do 
you use to Triple X for screen  based  facilities  across a  network,  
and do you feel that these could be promoted on a European wide basis?

     To what  extent, and in  what  timescale, do you  think that the  
ISO Virtual Terminal Protocal  will  have an impact on  providing the  
solution to the existing problems.


                          Yours sincerely,




                          B. A. C. Gilmore
