Baudot is a popular, sloppy usage meaning, these days, International 
Telegraph Alphabet No 2, which uses 5 bits of data with start and stop 
bits to maintain synchronism. The original 5-bit code used by M. Baudot 
was different and was sent synchronously (no start and stop).

No. Once the Figures shift character is sent the shift is 'sticky' like 
pressing Caps Lock. Everything is shifted until a Letters shift is sent 
and everything goes back to normal.

Hope that makes things a bit clearer.

Have a browse at https://www.rtty.com/ for much more info.
