Yes, can you isolate problem by getting one to work, then disable
it, get the other to work, then turn them both on ? Try initially at
low data rates to make sure this is not an overrun problem or in-
ability to handle composite traffic, eg. empty fifos on time, etc..
I got one to work at the desired baud rate but when adding the second it just follows the other. I have the pins defined and the ports on my computer correct too.
