All I remember of Baudot is the so-called Baudot code a 5-bit character encoding scheme with, I think, a set of 32 character alphabets, some of the letters reserved for alphabet switching. AFAIK those were used for text transmission or compression back in the wee old days when bits were hard to come by. The infamous Infocom (machine independent) z-code format used Baudot code to encode/compress text.
