/*
* Simple program to demonstrate the use of the tty drivers as the
* console interface. After initializing the serial console device,
* have the C library reconstitute its notion of the stdio streams.
*
* It prints out some stuff to the system console and then echos
* characters back until it sees ^D (EOF).
*
* NOTE: There is a nasty problem with the TTY libraries. They require the
* process lock, but many of the other device libraries take the process
* lock and then call printf, which results in a recursive process lock
* panic. Not sure what to do about that.
