As long as the line can handle 2*(number_of_keys) "chars", It should
be able to use the same up-and-down strokes. And, a cursory train of
thought would seem to indicate that a termcap-like table driven system
could be used at the far machine to make a keyboard independent
interface. Do many keyboards have more than 128 keys? The remote
machine SHOULDN'T have to treat remote keyboards differently. 

Perhaps we should begin to make a really SERIOUS distinction between
direct human input and other kinds.
