THE DEC VT102 TERMINAL TYPE
The DEC VT102 terminal is one of the most popular (and most
emulated) terminals in existence. It was developed by Digital
Equipment Corporation. The VT102 terminal has a large number
of functions. Telix supports all of these except for 132 col-
umn mode and double height mode. As well, Telix only emulates
double width mode, by adding a space after every character.
Telix fully supports both normal and application cursor mode
in VT emulation. The VT102 keyboard layout used by Telix is
stored in the VT102.KEY file, which is automatically read by
Telix when VT102 terminal emulation is selected. Once Telix
has loaded this into memory, the definitions can be edited
through the use of the Alt-K (Keyboard/macros) function.
The default keyboard layout is best suited for the (newer) 101-key
style keyboards with separate arrow and numeric keypads, and functions
keys across the top. In this layout, press F1 to F4 to simulate the
VT's PF1 to PF4. With the NumLock key down, the PC's numeric keypad
will simulate the VT's numeric keypad, while the arrow keys on the
PC's numeric keypad (with the NumLock up) or the separate arrow keypad
(at all times) will simulate the VT's arrow keys. Note that Telix will
only recognize the separate arrow keypad if you turn on the 'Enhanced
Keyboard' setting on the General Options screen of the Configuration
Menu.
Another keyboard layout is available that is possibly better suited to
older style keyboards with function keys on on the left side and no
separate arrow keypad and numeric keypad. To make use of this alter-
nate layout, while at the DOS prompt type:
ren VT102.KEY VT102101.KEY
ren VT102OLD.KEY VT102.KEY
This layout is similar to one used by many comm programs, in which the
normal function keys (F1-F10) represent the left side of the VT's nu-
meric keypad, while the shifted function keys (Shift-F1 - Shift-F10)
represent the right side, as follows:
Telix function Keys DEC VT102 Keypad

The arrow keys are also defined to send the proper sequences.
