In article  you write:
>typing. A small bell, driven by a  just like today ...

Smallest nit of the week -- telex machines are all Baudot five-bit code,
for which there's no such thing as a control key, just letter-shift and
number-shift.  The bell is some number-shift key.

[Moderator's Note: Well I believe it was the 'shift - 7' now that you mention
it; and of course control-G is Ascii 7. Weren't the 'number-shift' keys
essentially like control keys? How did they get line feed, carriage return,
ENQ (who are you?) and answerback without control codes?  My handy Ascii
chart here says control-E, or ASC(5) when sent polls the other end to
identify itself. What do you think?  PT]
