I don't know about its use as a terminal, but apart from Lander you could run
RT-11 on a GT-40. If so, some components would know to take advantage of the
display. In particular, there was GT-40 support in TECO, including a screen
mode editing macro similar to vtedit.tec. I haven't see that one,
unfortunately; it was probably pretty basic. You could also do without it,
simply issuing TECO commands while the GT40 was displaying the buffer content
in real time.
