SubjectRE: Possible Serial Kernel Bug
Date
From
Oliver,

I tried disabling flow control on the server with stty -F /dev/ttyS2
-crtscts, then echo sometext > /dev/ttyS2, but I get the same results
the echo command freezes will trying to send data to the client.

^^^^^^^
Could it be that hardware flow control is enabled on the server, while
it is disabled on the other side? What happens if you disable it with
stty -F /dev/ttySX -rtscts?
