New Revision: 199243
URL: http://svn.freebsd.org/changeset/base/199243

Log:
  Switch the default terminal emulation style to xterm for most platforms.
  
  Right now syscons(4) uses a cons25-style terminal emulator. The
  disadvantages of that are:
  
  - Little compatibility with embedded devices with serial interfaces.
  - Bad bandwidth efficiency, mainly because of the lack of scrolling
    regions.
  - A very hard transition path to support for modern character sets like
    UTF-8.
  
  Our terminal emulation library, libteken, has been supporting
  xterm-style terminal emulation for months, so flip the switch and make
  everyone use an xterm-style console driver.
  
  I still have to enable this on i386. Right now pc98 and i386 share the
  same /etc/ttys file. I'm not going to switch pc98, because it uses its
  own Kanji-capable cons25 emulator.
  
  IMPORTANT: What to do if things go wrong (i.e. graphical artifacts):
  
  - Run the application inside script(1), try to reduce the problem and
    send me the log file.
  - In the mean time, you can run `vidcontrol -T cons25' and `export
    TERM=cons25' so you can run applications the same way you did before.
    You can also build your kernel with `options TEKEN_CONS25' to make all
    virtual terminals use the cons25 emulator by default.

+	The default terminal emulation for syscons(4) has been changed
+	from cons25 to xterm on all platforms except i386 and pc98.
+	This means that the /etc/ttys file needs to be updated to ensure
+	correct operation of applications on the console.
+
+	The terminal emulation style can be toggled per window by using
+	vidcontrol(1)'s -T flag.  The TEKEN_XTERM and TEKEN_CONS25
+	kernel configuration options can be used to change the
+	compile-time default.
