Hello Bj”rn,

It is some time ago, but in my memory all messages in the TELEX
system were presented in Uppercase

That however was totally dependant on the presentation layer. All telex machines that I have owned and operated did in fact write upper case symbols, but there may very well have been other machines that did not want
their machines to shout at their readers. :)

The Baudot code is 5-digit code.
64 possible character codes minus 2 shift characters.
If both uppercase and lowercase were used, then it would
take 52 possible digits - just enough to do the alphabet.

5-digit numbers represent the same letters and numbers
in the telex system.

Since the Baudot code is still in common use in European
telex systems, only uppercase letters are allowed in the
international telex network.

Which leads to ISO 646.

I know, I know. What in blaze's hell ...

ISO 7-bit coded character set.
First edition in 1967.
Specified 7-bit character code (ISO/IEC 646).

Which brings you to -

CP866 (under DOS to write cyrillic script)

Telex only allows uppercase.
