   /TERMINATION_CHARACTER=character

   Specifies a character sequence for interactive terminal
   sessions that, when pressed twice, terminates the recording
   of an interactive terminal or DECwindows session. The default
   termination character is the sequence CTRL/P. When pressed once,
   CTRL/P temporarily suspends the recording session to introduce a
   recording function. For example, CTRL/P E (end automatic screen
   comparison) is the recording function instructing Digital Test Manager
   to terminate automatic screen comparison and to begin manual
   screen comparison.

   The termination character can be any single character, such as an
   asterisk (*),  or a control sequence, such as CTRL/P. To specify a
   control character, enter a circumflex (^)  followed by a letter.
   For example, to enter the termination character sequence CTRL/D,
   enter a circumflex followed by a D (/TERMINATION_CHARACTER=^D).
   You can also specify a termination character by its ASCII decimal
   representation. For example, you can use ASCII number 16 to
   specify CTRL/P.

   On interactive terminal tests, you can also terminate the
   recording session by entering the DCL LOGOUT command.
   If you do not want an accounting summary, enter the DCL
   STOP/IDENTIFICATION=0 command.
