Wikipedia is a great resource for computer/communication
standards. Baudot and its derived code ITA2 have only upper
case, with two characters LTRS and FIGS to determine whether
letters or numbers and special characters are being sent. <http://en.wikipedia.org/wiki/Baudot_code>
RIchard may be thinking of the code used by the IBM 2741
terminal which has upper and lower case shift codes. <http://en.wikipedia.org/wiki/IBM_2741>.

You said: "Even into today, HF marine safety and press bulletins and traffic

upper case because Baudot and SITOR RTTY use International Telegraph
Alphabet Number 2 which does not have lower case."
I'm having a problem with this. I had a Baudot machine, and as
I remember it, we sent either an upper, or a lower, case signal
(character) to place the machine at the far end in that case
position and it would stay there until we sent a corresponding
character to change it back again. I'm not familiar with ITA
Number 2. Baudot was a five bit code (plus a stop bit) for 32
characters. That was long ago.
