Update of bug #43604 (project grub):

Follow-up Comment #5:

Sorry for delayed response. I was wrong. The option sets some UART
configuration bits, so in any case it is up to used UART to actually implement
them. To my knowledge not many do it.

So we are back to lack of proper software implementation of flow control in
grub2.
