OK, "/dev/console" does not follow the standard termios stuff such as
ECHO, non-blocking, etc. It can be fixed.

I've got this working with some changes to pc386 console driver.

These device drrives do not exist. At least, with the snapshot that
I am using 19991117.
I'll wrap up one driver for them ( /dev/ttyS1 and /dev/ttyS2 ).
