       Terminal emulations
       ------------------------------------------------------------

       A terminal emulation is the method that RemoteAccess uses to
       communicate  with the  user's  software. The  most basic  of
       these is  straight ASCII.  The ASCII terminal  emulation can
       only display normally visible  characters plus a few others,
       such as backspace, linefeed and clearscreen.

       RemoteAccess supports two  additional emulations -  ANSI and
       AVATAR.  ANSI  is   currently  the  most  popular   terminal
       emulation in the bulletin board world; it has the capability
       to change text  colour, cursor position,  and can do  simple
       animations.  Some  implementations  of ANSI  can  even  play
       simple  tunes  at  the  user's  end.  ANSI  does  have  some
       drawbacks; each  special control code is  several characters
       long. To  change the  text colour  for  example, requires  a
       control  code of up to 8 characters. These lengthy codes can
       severely slow the  user's display, and  for this reason  the
       usefulness  of  ANSI at  speeds of  1200  baud and  lower is
       limited.

       AVATAR,  on the  other  hand, uses  control  codes that  are
       typically a quarter to  a third of the length  of their ANSI
       equivalents,  making it  usable  at lower  speeds. Not  only
       that,  but AVATAR  has  much more  advanced screen  control,
       making possible  relatively  complex animations  and  screen
       displays. AVATAR is a newcomer - there are comparatively few
       terminal programs  that support it, even  fewer that support
       it properly.  At  this  time  there  are  no  utilities  for
       creating AVATAR  screens. You can however  convert your ANSI
       screens to AVATAR with the supplied utility.

       RemoteAccess  uses  AVATAR  level  0+  (AVT/0+).   The  only
       terminal programs  which have been tested  successfully with
       AVT/0+    are   Joaquim   Homrighausen's   FrontDoor,   Adam
       Stanislav's TinyTerm  and  Adam Blake's Communique.  If  you
       make use of AVT/0+  you should make  it clear  to your users
       that they should  be  using  one of  these  two,  until more
       terminal programs  implement AVATAR support.
