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.
+
+ To prevent graphical artifacts, make sure the TERM environment
+ variable is set to match the terminal emulation that is being
+ performed by syscons(4).
