I've seen all the issues with 300 baud comms in the past ans also saw that the hardware serial core for the most recent build had the fixes updated to use 300 baud now. Problem is I'm using 1.0.1 and 300 baud still will not work correctly. It works at 1200 and above, but as soon as I change to Seria…
