  How is CONTROL/T disabled? 
 The Question is:
 
When our alpha boots up we loose our ability to do control-t.  When we log onto
 another alpha with the same terminal we can do control-t.  Do you know what
 would cause this.  Any help is appreciated!
 
 The Answer is:
 
  Something (or someone) has probably directly or indirectly disabled the
  Control/T processing during the system startup.
 
  Try a test with a manual SET CONTROL=T, the appropriate SET BROADCAST,
  and the appropriate SET TERMINAL/BROADCAST command, and see if it works.
  If so, you are left to root through the local startup to see what has
  happened.
 
  Otherwise, you are left to contact the Compaq Customer Support Center
  for assistance in resolving this.
