Subject: [FreeBSD 2.0-950112-SNAP] - SIO bug, driver discards chars
Organization: Lionheart Software

There is a bug in the SIO driver that causes it to discard characters if
the tty is in raw mode and there is no space left in the clist - even when
RTS/CTS is enabled.  The SIO man page calls this a bug in the application
code; what idiocy.

Has anyone fixed this already?  I'd hate to fix something and then find out
there's already a working version out there.  Looks to be a fairly involved
effort, too - gonna have to rework some of the way the buffering is done so
that the driver can throttle back via RTS when it must.
