#CONFIGURING MINICOM SERIAL#

Remove paramters with empty arguments (like -dtb and -sbat ) and add serial and terminal modules to the end of the grub-mkimage parameters list.ĥ. Replace -config '/boot/grub/PLATFORM/load.cfg' to -config '/boot/grub/PLATFORM/early-grub.cfg'

Edit grub-mkimage parameters from step 1 (the grub-install output): Add the following lines at the beginning of /boot/grub/PLATFORM/early-grub.cfg (change those lines according to desired configuration as described above):Ĥ. Copy /boot/grub/PLATFORM/load.cfg to /boot/grub/PLATFORM/early-grub.cfgģ. You can reboot the system to check if it boots properly, but you should save the output of the commahd above - it will be hecessary at step 4.Ģ. # grub-install -verbose /dev/YOUR_BOOT_DISK 2>&1 | grep grub-mkimage # grub-install -verbose 2>&1 | grep grub-mkimage Run the following command to generate /boot/grub/PLATFORM/load.cfg and see the correct grub-mkimage parameters for your system:

#CONFIGURING MINICOM PASSWORD#

To get the GRUB cryptodisk password prompt on the serial console a few extra configuration steps are required:ġ. The /boot/grub/PLATFORM/load.cfg file gets overwritten each time grub-install is launched. This happens because the grub-install has special behavior for GRUB_ENABLE_CRYPTODISK=y and will create early config placed in /boot/grub/PLATFORM/load.cfg but grub-install ignores serial console configuration from /etc/default/grub for GRUB first stage. When GRUB is installed to an encrypted /boot/ partition - GRUB first stage (core.img) will show Enter passphrase for hdX,gptY: password prompt only on platform console and will not show anything in serial console even if all serial console configuration steps were done properly.

#CONFIGURING MINICOM MANUAL#

Read GRUB's manual on Using GRUB via a serial line and the serial command for detailed explanation of the available options. GRUB_SERIAL_COMMAND='serial -unit=0 -speed=115200' For COM1 ( /dev/ttyS0) with baud rate of 115200 bit/s: Next add the GRUB_SERIAL_COMMAND variable and set the options for the serial connection. When using GRUB with a generated grub.cfg, edit /etc/default/grub and enable serial input and output support: The configuration instructions below will enable boot loader menu selection, boot messages, and terminal forwarding to the serial console.Ĭonfigure console access on the target machine Boot loader GRUB

#CONFIGURING MINICOM WINDOWS#

The administering machine can be any Unix/Linux or Windows machine with a terminal emulator program (PuTTY or Minicom, for example). Installation of Arch Linux is possible via the serial console as well.Ī basic environment for this scenario is two machines connected using a serial cable (9-pin connector cable). Here are the steps to enable UTF-8 support in Minicom on Linux: Step 1: Open the Minicom configuration fileįirst, we need to open the Minicom configuration file using a text editor such as Nano.An Arch Linux machine can be configured for connections via the serial console port, which enables administration of a machine even if it has no keyboard, mouse, monitor, or network attached to it. Step-by-Step Guide to Enabling UTF-8 in Minicom Without UTF-8 support, characters may be displayed incorrectly or not at all. If you are working with devices that use non-ASCII character sets, such as Japanese or Chinese, you may need to enable UTF-8 support in Minicom to properly display the characters. Minicom is pre-installed on many Linux distributions, including Debian, Ubuntu, and CentOS. It is commonly used for tasks such as configuring routers and switches, but can also be used for debugging other serial devices. Minicom is a terminal emulation program that allows users to interact with remote devices through a serial connection. Step-by-Step Guide to Enabling UTF-8 in Minicom.
