OSBYTE &7E (126) - Acknowledge ESCAPE Condition

   On entry:
       no parameters
   On exit:
       X=0   There was no Escape condition pending.
       X<>0  There was an Escape condition was pending.

If Escape side effects are enabled with OSBYTE &E6, then those side effects are attempted (flushing buffers, closing Exec file, etc). Then the Escape condition is cleared and the Tube is notified.
