Description Jan "Yenya" Kasprzak 2001-10-08 19:23:45 UTC 
Description of Problem:
When I try to set up GRUB for serial console, I cannot set the speed
different than 9600 bps (tried 115200, 38400 and 19200). I have the
following commands in /boot/grub/grub.conf:

serial --unit 0 --speed 19200
terminal serial

However, the boot loader still communicates at 9600 bps.
Both BIOS setup and kernel is capable to communicate at different
speeds (the console=tty0,38400n8 kernel parameter works as expected),
I just cannot change the speed of GRUB.

Version-Release number of selected component (if applicable):
grub-0.90-11 (actually this is a RPM from yet-unreleased Red Hat 7.2 - I am
one of the official mirrors).

Additional Information:
The machine is Tyan Thunder K7 with dual Athlon/MP @1.2 GHz. This mainboard
BIOS setup can also work over the serial line. It is just a bit slow
at 9600 bps, so I've wanted to set the whole boot process up to the higher
speed.

I'll try to take a look at this in the near future
Comment 2 Jeremy Katz 2002-08-11 20:19:46 UTC 
Should work with what's in 7.3 and rawhide
