Hey Jelle! The serial line protocol defines one out of band sequence. Only one unfortunately. This is triggerd with the break or pow_break commands. Usually they behave identical, or only one of them works. you already found the keybinding.
The exact effect of break or pow_break depends on the hardware that is connected to the other end of the serial line. Triggering sysrq is pretty much the best thing that a break can do. All else depends on the second keystroke you send after the sysrq. cheers, JW- On Thu, May 7, 2015 at 3:07 PM, Jelle de Jong <jelledej...@powercraft.nl> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Hello everyone, > > How do i sent a ctrl-alt-del over screen serial console? > > I occasionally have systems hanging in grub-rescue and a simple > ctrl-alt-del signal would reboot them. > > But I have been unable to figure out how to do this with grub. > > I know commands like c-a b b send a sysrq reboot, is there a ctrl-alt-del? > > Kind regards, > > Jelle de Jong > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1 > > iJwEAQECAAYFAlVLY4EACgkQ1WclBW9j5HnRywP/QwWytK0pg6LgARSP6cnRDCV7 > yVtlC9trUkDeoxliKcDFl1mcmjX80NBjem6HomIZ1ou9T2XVDPa31L0w+c1jDWGh > fyOubY3g82XDk122ekM7DZg1FutjQGNt1dV+FQ+WJf3upjfi9ahzobfK0oE51sAS > 9dz2or2bpLDSZS87+D0= > =BVss > -----END PGP SIGNATURE----- > > _______________________________________________ > screen-users mailing list > screen-users@gnu.org > https://lists.gnu.org/mailman/listinfo/screen-users _______________________________________________ screen-users mailing list screen-users@gnu.org https://lists.gnu.org/mailman/listinfo/screen-users
