I'll probably whip up something rudimentary in the next couple days, but full blown support in ddb would be nice. BTW has anyone used the watchpoints claimed to be available in ddb? It looks like it goes through the vm system, does that make sense? The man page says that watchpoints on user space work best, what sense does it make to put a kernel watchpoint on a user address? > >On the other subject, changing out of X into character mode: I believe SCO uses dbtty(0|1) to switch from vt0 to sio0 on the fly, they also note that the serial line is not initialized in any way, so if you've got a mouse sitting there, it's now you're console. I'd say this is probably one of the better ways to handle this situation. > >Greg > > eric -- erich@lodgenet.com http://rrnet.com/~erich erich@rrnet.com
