FT232R The FT232R supports all standard baud rates and non-standard baud rates from 300 Baud up to 3 Megabaud.
Achievable non-standard baud rates are calculated as follows -

Baud Rate = 3000000 / (n + x)

where n can be any integer between 2 and 16,384 ( = 2 14 ) and x can be a sub-integer of the value 0, 0.125, 0.25,

0.375, 0.5, 0.625, 0.75, or 0.875.
