I'm not yet up to v28, but M-x suspend-frame RET does as it would expect
for me. OTOH, In a GUI instance M-x suspend-emacs RET complains that Emacs
can't be suspended while there is a visible frame. It does work for me in
an instance started with -nw. In fact, help on suspend-frame shows that
it's a bit higher level, calling the correct lower level function depending
on environment.
