All standard 16550 family ports support 8 bits _and_ parity.  Ancient
serial ports did have a restriction, but that restriction is no more.

You actually mean 2 stop bits.  (There is _always_ one stop bit).

I read your first mail, but couldn't really grasp the details of your
problem.

Are you trying to direct console _output_ to ttyS2 and the VGA card, yet
still accept input from the PS/2 keyboard?  And then when you try to set
this up, you get garbled characters via ttyS2?
