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  and  Adam
    Stanislav's TinyTerm. 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.
