Re: Lilo On The SErial Port

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


What that does it tell 'lilo' that when your system boots, it's
going to tell the kernel that serial=1,9600.

I don't know exactly if that's needed or not.  But if serial
support is compiled into the kernel, you will need to reboot
for the new settings to take effect.

Erm, I hope that helps.
