I use conserver conserver conserver host null-modem serial cables test machine label test port AA ------------------------- sio0 serial console testnmi port BB ------------------------- sio1 NMI I start two conserver sessions, one using test (for the console access) and one using port testnmi (for NMI). When I need an NMI, I just press return or space in the session using port BB. This only works when the test machine runs an SMP kernel with DDB and the virtual NMI pushbutton patch. No programs on the test machine should open sio1, since that could cause interrupts (which are now NMIs). > can a paperclip be used to generat the interupt by connecting pins 2 and 3? I haven't tried that. - Tor Egge To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
