An adjunct to the point I made in another thread, namely that the use of certain crystals in order to ensure the availability of the widest range of asynchronous baud rates was, in fact that making that choice was quite limiting.
quite limiting how?

The simple reason people don't use Mode-0 is by no means what you state it is because it can not "talk to the world"

1)Show me a PC or a RS485/RS232 industrial sensor or an automobile, or a cellphone or a serial VFD that can communicate with mode 0.

2) show me how to communicate with a 9600 interface on e.g. a cellphone with a 12MHz crystal using a derivative without T2.
Communicate with a device that can handle a frequency deviation from 9600 or higher of more than 5% (a very generous amount, most can only handle ~3%)


If you can do the above, I'll shut up
