barmar@think (Barry Margolin) asks why -8 uses RAW, not CBREAK.

In article <88236@lll-winken.LLNL.GOV> casey@gauss.llnl.gov (Casey Leedom)
answers:

Well, yes and no.  The real reason rlogin -8 uses RAW is that it was
coded under 4.2BSD, where raw mode was the only way to get 8 bits.
LPASS8 appeared in 4.3BSD (imported from Utah).

Now that 4BSD has a POSIXified tty driver, all of this should be redone.
But when the new ``bstreams'' code is working things may change again
anyway.
