What do you mean "doesn't recognize"? How are you trying to configure serial output and what happens when you do this? > > How does the recognition work? Where is this part documented? Do you > have a list of known good devices? I assume that (when not using native grub drivers) it's up to the BIOS to detect and enumerate serial devices. Documentation for using a serial terminal from grub is available here: http://www.gnu.org/software/grub/manual/grub.html#Serial-terminal you'll probably also want to look at GRUB_TERMINAL_OUTPUT, GRUB_TERMINAL_INPUT, and GRUB_SERIAL_COMMAND in http://www.gnu.org/software/grub/manual/grub.html#Simple-configuration . -- Jordan Uggla (Jordan_U on irc.freenode.net) _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
