Fixing scrambled terminal display

A scrambled terminal responds to keyboard input but the display is incorrect. To fix a scrambled terminal:

1. Check the terminal type (TERM) for the user with the env command. If the terminal type is incorrect, reset it. For example, to set the terminal type for a Wyse 60, enter:
   
   TERM=wy60

   After resetting the terminal type, reinitialize the terminal by entering tset with no arguments.

2. Reset serial line characteristics with the following command:
   
   <Ctrl>j stty sane <Ctrl>j
