You're absolutely right in that you have to consider other risks, particularly those associated with cable characteristics, particularly length. However, from what I've gathered about Erik's work, his comm-paths are under 1 meter, and apparently, most of the time, under 50 mm, and between "standard" devices that use NRZ in asyncformat and protocol.

Oddly enough, I based my original statement about baud rates, possibly in that "other" thread, on your post indicating that, with T2 at the BRG, 12 MHz would work fine.

In the many years I've worked with microcontrollers, I've noticed only about 1 in 20 applications that relied on async communications. Erik seems to believe that it's much more than that. Clearly he works in a different world than I.

In which industry do you work? Where does it demand use of the "standard" async protocol?
