I remember printing 65wpm (not 66) on a 15 with no problems and no 
adjustments; that is 60 wpm/45.45 baud with one stop bit rather than 
1.42. I have no doubt a 28 could do it even better. I'd consider two 
stop bits to be too much so I would use 1.5. I know the extra length for 
the stop bit is a "catch-up" safety margin but I have forgotten why it 
is 1.42 rather than 1.5 on the mechanical printers.
