I don't think there are many terminal emulators left that emulate a  
VT-100 strictly.  Most add some features a VT-100 didn't have (e.g.,  
ANSI color, Unicode) and leave out some stuff that is rarely used or  
hard to implement (double-height mode, application-controlled  
keyboard LEDs, 132-column mode, etc.)  Generally they're actually  
"emulating" some cross between a VT-100 and an ANSI terminal, or a  
VT-100 and an xterm.

Actually, the most thorough VT-100 emulator I can remember ever using  
was the old MacOS serial terminal program Red Ryder.  It *did*  
emulate double-height mode and keyboard LEDs, the latter via a pop-up  
window.
