Hello GRUB community ! In our company we use GRUB to boot a couple of embedded machines in complex setups. Further we use automatic test scenarios, where test tools control the machine via serial console or ethernet.
For the serial console I have some ideas for improvements. 2 Points: 1) As GRUB now shifts the command line, it it exceeds the line length, the `serial_getxy' should not do a real terminal query any more. In setups not using a xterm but editor `emacs' or using `expect' cannot handle this easily. As we always stay in the same line, `x' can be calculated. For `y' I have to check, if it is needed for the command line editing. 2) DUMB terminal support for serial line: The menu should work a little bit different. My prefered solution is, that every menu selection has to be confirmed by return. On the first keypress the countdown is stopped (as now implemeted), then there is not a up down, but a selection per number, like `3<ENTER>'. A `<ENTER>' alone can select the default entry. To get in command line mode a `c<ENTER>' must be given. To edit the default entry use `e<ENTER>', to edit entry 3 (for example), use `e3<ENTER>'. So also canonical terminals can be used to control GRUB inclusive the menu. With this change, it would be easy to use the GRUB menu out of `emacs' or `expect'. Chnages for point 1 are quite simple (my opinion). For point 2 the control logic must be addepted to the usage of <ENTER> without breaking the default menu behavior. What do you think of this change ?
