- Subject: Real TIOCSETP
-
- tty.c, file.h, xbios.c: ++entropy@terminator.rs.itd.umich.edu
- Add a real TIOCSETP (differs from TIOCSETN in that it waits for
- the output buffer to be empty if the device supports TIOCOUTQ.)
- Remove a kludge in rsconf() which is not needed if a real TIOCSETP
- exists.
