It's nothing to do with mush, Bart. Sorry to have bothered you. The tty driver in SCO System V/386 3.2.0, with ISTRIP on will match a 0x80 from the keyboard with the 0x0 that the suspend character has been set to (ie. when not in use) and send a SIGTSTP to the process. Now, can someone tell me whether this is right or wrong ? What does BSD do in this case, and what does POSIX say ? My mush binary was compiled under Xenix, which *doesn't* have SIGTSTP, and I don't have a jobcontrol shell yet, so the process just stopped where it was. :-) I didn't notice the 'T' in the ps listing before -- I'm not used to stopped processes in a System V format ps output :-) -- my .signature is on holiday
