VMS Help DTM, RECORD, Qualifiers, /REALTIME  *Conan The Librarian (sorry for the slow response - running on an old VAX)

   Instructs Digital Test Manager to record and forward keypresses to the
   application as they are entered, and not when the application requests
   them. By default, Digital Test Manager records keypresses and places
   them into the terminal input buffer for an application when the
   application reads from the terminal.

   This qualifier is intended for use in recording tests where an application
   will not read from the terminal until data appears in its terminal buffer.
