VAX Only

   $ PEEK/RT_ENABLE      ! VAX Only

   When an RTA unit logs in it must issue a PEEK/RT_ENABLE command before
   it can be watched with Peek/Spy. (This command must also be used before
   a VAX RTA can start NDC's VAX MultiSessions screen-saver which is used
   for the Peek/Spy initial screen refresh on VAX.)

   PEEK/RT_ENABLE enables watching of the single RTA terminal from which
   the command is issued, without affecting other RTAs on the system.

   Enabling watching of RTAs on AXP uses PEEK/SAVE_SCREEN instead of
   PEEK/RT_ENABLE.
