by "break" I mean a serial break condition. Take the Tx line out of your box and bring it negative 3-5 volts for a short time, that will be a break.
Seriously, the break will need to be sent from the piece of equipment that is connected to the other end of the serial line. It isn't a telnet issue at all. There should be a way to drop into a command mode on the livingston (I have never used one, so I don't know how), and send a RS-232 break to the remote side. After that go back to terminal mode, you should be at a DDB prompt. "trace" should give you what we want to see. Also, if you can configure 'dumpon' and 'savecore' (man savecore, see 'dumpon' in /etc/rc.conf), at that prompt enter 'panic' to get a core dump of your system... you may have to enter 'panic' more than once. I have a spare machine here.. I will try my program on it shortly.. I don't feel like crashing my home machine again... it is in X so DDB doesn't work, and I need to hard down it with the reset button. Plus it is a good 15 minute walk to just get there. -- David Cross | email: cro...@cs.rpi.edu Systems Administrator/Research Programmer | Web: http://www.cs.rpi.edu/~crossd Rensselaer Polytechnic Institute, | Ph: 518.276.2860 Department of Computer Science | Fax: 518.276.4033 I speak only for myself. | WinNT:Linux::Linux:FreeBSD -- David Cross | email: cro...@cs.rpi.edu Systems Administrator/Research Programmer | Web: http://www.cs.rpi.edu/~crossd Rensselaer Polytechnic Institute, | Ph: 518.276.2860 Department of Computer Science | Fax: 518.276.4033 I speak only for myself. | WinNT:Linux::Linux:FreeBSD To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
