The "Liberty 120" terminals age from mid-1992, made by Liberty-Electronics
in San Francisco have a serial port and a parallel port. They're very basic,
and designed similar to the WYSE 85's. From what I can tell, they were
internationally released, and emulated many terminal types. Because of this,
there are some confusing things to the Liberty terminals, and still several
things I don't know about.

 I've tested them for all the graphic formats I know of, and nothing works.
They don't respond to any soft-font commands either. It can emulate VT-52,
VT-100, VT-200, VT-300, Freedom ONE, TeleVideo 950, TeleVideo 925, Lear
Siegler ADM 31, ADDS Viewpoint A2, Dumb Terminal/PC Terminal, WYSE 50, WYSE
60, WYSE 120, WYSE 150. The WYSE emulations are not complete, and I haven't
been able to test anything else other than the VT specifications, which seem
complete except for the escape codes that DEC didn't tell anyone about, and
since I don't know any of them I can't tell you if even they work or not.

 Keyboard setup is dependant on the emulation settings, and so are the
options in the setup menus as well, so that should always be set up first.
In the VT modes, Pressing control-escape brings you into a "simple" setup
mode, where the options are all on a single simple line down the bottom of
the screen. Pressing Shift-Escape takes you into a larger full-screen setup
on several pages.

 In any other modes, pressing scroll lock will open the simple setup system,
pressing shift-scroll lock will bring up the full-screen setup system.
Shift-break resets the system. If you ever get completely stuck, you can
open up the bottom and on the circuit board there is a little button-battery
(like in a watch) that holds the settings. If you take that out for about 15
minutes, the terminal will be completely reset.

 In the full-screen setup mode, there are some additional functions you can
access. Since I don't have the documentation, and Liberty-Electronics
haven't replied with any help, I can't be sure. One day my cat sat on my
keyboard while I was in setup mode one day. Something happened and the
terminal reset. I tried to continue my setup-session, but I kept being asked
for a password, and I could never work out ever again how to get in to set a
password! That required removal of the battery...

 There is one function I'm confident about. It's a full screen and keyboard
test. This helps aligning the screen if you're into fiddling with the
trimpots in the back of the video section of the terminal. Before you start
this function, be warned.. You have to remove the battery to stop the
terminal from forever testing itself! The test doesn't stop, and cannot be
stopped by pressing a key combination (AFAIK). To access it, get into the
full-screen setup mode, then press shift-F1. There is another test
accessible via shift-F2.
