Q: What should I do when the system is slow or hung up?

A: Follow these suggestions:

  • If you're logged into the UCSD mainframe and "X SYSTEM" is showing in the lower corner of the TCP3270 screen, it indicates that the computer is "thinking."
  • Do not hit "Enter" on your keyboard.
  • If "X SYSTEM" shows for longer than two minutes, close the TCP3270 program, then attempt to log on again.
