The Start Keystroke Intercept function allows a workstation application to filter any keystrokes sent to a session by a terminal operator. After a call to this function, keystrokes are intercepted and saved until the keystroke queue overflows or until the Stop Keystroke Intercept (53) function or Reset System (21) function is called. The intercepted keystrokes can be:
  • Received through the Get Key (51) function and sent to the same or another session with the Send Key (3) function
  • Accepted or rejected through the Post Intercept Status (52) function
  • Replaced by other keystrokes with the Send Key (3) function
  • Used to trigger other processes
