[GreenKeys] shockingly basic question - Teletype Model 33 ASR

[Jim Haynes]

All the 33s and 35s generate 11 unit code.  1 start bit, 7 data bits, one
bit which may be even parity or may be marking, and two stop bits.  That's
where 110 baud comes from. 100 wpm = 10 chars/sec and each char contains 
11 bits.  The reason for two stop bits is the difficulty of making a
mechanical selector that is reliable at 100 wpm.
