[GreenKeys] shockingly basic question - Teletype Model 33 ASR

[Keith Lueck]

 Jim & Wayne are spot-on, of course.  I learned the hard way that you best include the parity bit - even though the 33 doesn't give a whit about parity...  My machine was occasionally producing errors when I was feeding it 7 N 2.  Wayne Durkee set me straight, and, viola, when I sent it 7 M 2, everything was 100% ducky.

 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.
