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.
