E)cho.  The utilities "E" command lets the caller set who is to echo.
"Echo" means to send back what the caller types.  If nobody echoes,
callers cannot see what they type.  The options are:

  C)aller's software.   RBBS does not echo.  Callers should set
      echo on in their communications software.

  R)bbs.  RBBS echoes what it receives.   Normal mode in RBBS.

  I)ntermediate host.  A computer between RBBS and the caller does
      the echoing

Tips:  
1. The fastest performance is C)aller's software, because echo does
not have to wait to transmit character and the get it transmitted back.

2. The safest form of echo is RBBS.  That way the caller sees what
RBBS really received rather than what was sent.

3. Intermediate host echo can be used when RBBS is accessed through
other computers, such as as Compuserve.

4. Use C or I if it seems to take a long time for what you type
to appear on your screen.  This is a common problem when typing
must pass through several computers, e.g. on PC-Pursuit and
Compuserve.
