         Abstract:  

         TEM  provides  "dumb" terminal emulation over a full duplex TT:
         line.  It allows the user to "become" a terminal  on  a  remote
         system, and to do ASCII file transfer between systems.  TEM has
         been used to communicate with RSX, VMS, RSTS, and TOPS-20  sys-
         tems, as well as non-DEC equipment.  It requires no software on
         the remote system (and therefore has no error checking).  

              In  addition to the basic functionality, TEM can automati-
         cally issue canned commands to smart modems  at  the  beginning
         and  end  of a session.  The user can also select from the fol-
         lowing features:  
             * Local Echo.  
             * Automatic linefeed on carriage return.  
             * Passthru of control/s, control/q, control/o and control/x
                 to the remote system.  
             * User selectable attention and end-of-file characters.  
             * Inbound and outbound character mapping.  
             *  Specifiable  record  delay and prompt character for file
                 transfer.  
             * Parity generation and checking.  
             * Eight-bit character support.  
             * Input line analysis, in ASCII, binary, octal, decimal, or
                 hex.  

              TEM  requires  at  least  RSX-11M+  V2.0, VAX-11 RSX V2.0,
         RSX-11M V4.0, or RSX-11S V4.0.  If  running  under  RSX-11M  or
         RSX-11S,  it requires the full-duplex TT:  driver, get/set mul-
         tiple characteristics, and unsolicited  input  AST's.   Correct
         access  of  named directories and files numbered in decimal re-
         quires the FEAT$ directive.  The GIN$ directive is used to pre-
         vent  nonprivileged users from using TEM to read files that are
         none of their business (eg:   LB:[0,0]RSX11.SYS).   An  attempt
         has  been  made  to  conditionalize TEM for RSX-11M V3.2, but I
         have no way to check it.  TEM can be initiated from and commun-
         icate  with any reasonable serial device, but there may be res-
         trictions if not being used on a TT:-type device.
