I have never gotten the communication to work correctly using manual flow control, but it should not be causing your board to restart. I’ll look into it.
When using manual flow control, you have to set the direction pin high or low to change directions. The library does this, but I think there is a timing issue or something because my attempts at using it with a max485 and level shifters compeletely failed.
