Depends, is the M15 or M19 setup for S bell (USTTY) or J bell (CCITT
ITA2 standard)?

In both cases, letters shift is fully compatible. Figures shit is also
mostly compatible, except that F, G, H are Cyrillic characters (since
ITA2 does say the figure shift of F, G, H are national use, so they
can vary depending on the language). Figure shift J, instead of
producing a bell gives you another Cyrillic character, and figure
shift D gives you a WRU.

If you used a a USTTY (S bell) machine... S will give you an
apostrophe. Bell will give you a 'yu', dollar sign will make the other
machine answerback at you, and the exclamation mark, ampersand, and
octothorpe (pound sign) will also give you Cyrillic characters.

This presumes no body sends a null. Because if you do the MTK-2
machine starts typing in Cyrillic, while the M15 will happily continue
on in whatever mode it was in. Oh, and when the MTK-2 machine switches
to Cyrillic from Latin, you'll at least get text that is somewhat
transliterated.


Cheers,
Christian
