Actually there was a 6 bit code called TTS that did include case but
could be printed on a Baudot printer as all upper case. In Baudot the
most significant bit is sent first, but the added bit in TTS is shown as
the most significant. But in TTS the 5 base bits of Baudot are sent
first, then the upper/lower case bit is sent. That oddity caused a lot
of extra work when I worked up a computer connection from a TTS circuit
25 or 30 years ago. The programmer figured it out in a week of trials,
then I went to that adjacent AP office and confirmed it by looking at a
receive cam. The TTY service people there didn't believe either until I
proved it with the cam.
Baudot and TTS predate ASCII by 20 or 30 years. And they predate
computers by nearly that much. ASCII came decades after IBM Hollerith
codes.

Perhaps you could have paid a bit more to AP for a TTS printer on the
same circuit.

Now where's that shift up and shift down character for Morse or
Continental code?
