VT100 supports these short escape sequences when in VT52 mode.

Maybe the problem is that you didn't issue the escape sequence to put
your VT100/emulator into VT52 mode first?

That is one cool looking video terminal, for sure :-).  Physically it
doesn't look like any Tektronix terminal, nor does the on-screen font
shown in those photos.  Most terminals ultimately ended up emulating
two models: VT100 and Tektronix 4010/4014.  The former was for
character based displays and the latter was for graphics.
