If I remember correctly, the original TENEX ^T sent a signal (or its TENEX equivalent) to either the entire process tree or to the top-level exec, which woke up and did the "ps". Just out of curiosity, has anyone implemented a UNIX ^T as just another interrupt character and hacked a shell to catch it and do a "ps"? Guy Harris {seismo,ihnp4,allegra}!rlgvax!guy
