We need ncurses to get the codes for these keys right. Only plain text
keys can work without ncurses.

Simulate pressing the corresponding key on the PC keyboard. But that can
only work when using the Linux screen driver or running xbrlapi. And of
course you risk getting a loop :) since the simulated keypress event
will probably go into the xterm where you are running the TTY braille
driver, and thus simulating it again, etc.
