uplcom broken by MPSAFE TTY commit?

[Christian Weisgerber]

Has anybody noticed problems with uplcom after ed's MPSAFE TTY
commit?

ucom1: <FTDI USB HS Serial Converter, class 0/0, rev 1.10/2.00, addr 4> on uhub2
ucom2: <Prolific Technology Inc. USB-Serial Controller, class 0/0, rev 1.10/3.00, addr 5> on uhub2

I'm seeing incomplete input followed by repetitive spew on ucom2.
The uftdi-based ucom1 seems fine.

ucom2 is hooked up to the serial console of an OpenBSD box.  The
getty there issues a banner like this:

OpenBSD/alpha (kemoauc.mips.inka.de) (tty00)

What I now get in cu(1) is a stream of this:

OpenBSD/alpha (kemoauc.mips.in
OpenBSD/alpha (kemoauc.mips.in
OpenBSD/alpha (kemoauc.mips.inka.de) (tty00)

OpenBSD/alpha (kemoauc.mips.in
OpenBSD/alpha (kemoauc.mips.inka.de) (tty00)

OpenBSD/alpha (kemoauc.mips.in
OpenBSD/alpha (kemoauc.mips.in
OpenBSD/alpha (kemoauc.mips.inka.de) (tty00)

OpenBSD/alpha (kemoauc.mips.in
OpenBSD/alpha (kemoauc.mips.in
OpenBSD/alpha (kemoauc.mips.inka.de) (tty00)

[... and it keeps spewing ...]
