Title: when and why to use 1, 1.5 and 2 stop bits in UART
Post by: titan_amit on June 11, 2011, 10:08:17 am

I read at several places that 1.5 stop bit is prescribed for use only in the case of 5 bit data, 2 bit for longer data length and 1 bit stop can be used for any data length. I wanted to know reason for these recommendations.

My advice is to use one stop bit unless you have a good reason not to. You will likely never encounter a good reason. Compatibility with legacy hardware might be one.
