Wow, that’s some great research there! Congratulations on chasing down that bug! 
We chose 14400 and 28800 as the baudrate specifically because they were uncommon, and so unlikely to conflict with the baudrate that the application might wish to use.
There’s no consequence from changing the value other than a possible collision with the application baudrate. As we’re discussing this, I’m thinking that the system should allow the value to be configurable, rather than it being hard-coded. I’ll add that to our backlog!
