i'm switching a server to UEFI boot -- and bumping into issues with serial
console config
running
grub2-install --version
grub2-install (GRUB2) 2.04
rpm -qa | grep ^grub2
grub2-2.04-lp151.7.1.x86_64
grub2-branding-upstream-2.04-lp151.7.1.x86_64
grub2-i386-pc-2.04-lp151.7.1.noarch
grub2-systemd-sleep-plugin-2.04-lp151.7.1.noarch
grub2-x86_64-efi-2.04-lp151.7.1.noarch
with
uname -rm
5.5.6-24.g4a830b1-default x86_64
my grub config currently includes,
GRUB_TERMINAL_OUTPUT="gfxterm serial"
GRUB_SERIAL_COMMAND="serial --unit=0 --speed=115200 --parity=n --word=8
--stop=1"
GRUB_CMDLINE_LINUX=" ... \
console=tty0 console=ttyS0,115200n81 \
earlyprintk=serial,ttyS0,115200,keep"
connected to the serial console from a local desktop running 'minicom', output
_does_ appear as expected.
formatting -- specifically carriage returns / line feeds -- however, _starts_
out OK, and _finishes_ OK once reaching the login prompt, and after.
but, in the 'middle', carriage returns go wonky ...
here's what I see in desktop's 'minicom' connected to server's serial port:

what needs to be configured to get the serial console to output consistently
'well behaved' formatting from start of output to login prompt, and onward?
