[BusyBox] problem using Inittab

[Brad Barrett]

Hmm... 8-N-1 is default, so all you really need is to be able to set ttyS0 to
115200.  This can be accomplished with "stty 115200".

Try changing it to:

ttyS0::respawn:-/bin/sh -sc "stty 115200"

or add:

ttyS0::wait:-/bin/sh -c "stty 115200"

I have never tried this (my boot monitor can pass cmd line parameters) but both
should work, in principle.  If you need to set parity, data bits, etc, there are
other stty options for those...but I can't confirm off hand that Busybox stty
supports them.

How can I set the serial port parameters (115200n8) if I type:
ttyS0::respawn:-/bin/sh

If you don't want a login at all you could probably replace your getty
line with something like

ttyS0::respawn:-/bin/sh

And BTW: Do you have a user root in your /etc/passwd?
