What makes you think that GPS' run-panel emulates VT100?

And, is it the GPS GUI where your output goes?

Anyway GPS is GTK-based. Presumably, it uses the GTK text buffer object
where the program standard output goes. So you should look here:

to learn for how to control it and its view:

If you mean something else, like console output, then depending on the OS
and the terminal emulator you might need different control sequences. If
you want to use the VT100 ones, you should get a VT100 emulator.

BTW, Windows' cmd.exe does not emulate VT100.
