of digital video recorders popular in Europe and Australia.
These devices have a USB client port which can be used to upload and
download recordings (and other files, such as MIPS binaries for execution
on the DVR's CPU) to/from their internal hard disk, in addition to some
other operations on files and directories.
NetBSD and boot NetBSD (!).
The program was run from within boot-only, NetBSD-as-bootloader as a userlevel
program, then in-kernel boot code loads another NetBSD image and jumps to
it.
These programs are no longer setuid, and now lock devices with flock,
not file locks in /var/spool/. They will no longer lock against UUCP
itself unless we modify UUCP to lock with flock, but this seems highly
unlikely to be an issue in the present day.
This means we can get rid of the suid/sgid parts of the code (which
have been removed). The program is now installed with normal permissions.
To prevent accidents, we now flock the tty line, attempting to get an
exclusive lock.

(a.k.a. "tandem" mode). While we're here, fix a buglet with --halfduplex,
and add --flow {hard, soft, none}. Note that you can't get *both* hard and
soft flow control using the command-line option; if you want that, you
have to set the variables in tiprc or with ~s once tip is running.
Move all setting of vars.c named variables to *after* the call to vinit().
Turn it off by default -- it hardly saves any space, but it's
one of the reasons why the executable is installed setuid, and
other versions of tip/cu don't write a log file anyway. We can
add syslog support later if we ever really want this back, the
file-writing is all encapsulated in log.c.
but with some long options added for Taylor 'cu' compatibility, and
with some bugs fixed (in particular, the handling of -# now works as
documented and does not overwrite argv).
the others (maybe "Courier", but I doubt it) we can easily enough turn
them back on.
Saves 20-30K depending on platform. Not totally insignificant, since this
often goes on install media, or very small systems.
Maybe we get away with this (at least on 32bit archs) because the structure
is 24 bytes and I bet the minimum allocation size is 32.
