Hi All,

I am using a powerpc8548e custom hardware and testing flow control on
it. I have cross-wired the RTS/CTS of the board with my host terminal.
I find that when I am reading from the powerpc, it does not change the
CTS signal when it is running out of buffers and hence it is dropping
bytes.

I referred to something similar at http://lkml.org/lkml/2007/7/26/46.

Can anyone please tell me if this flow control needs to be done by the SW?

thanx!
Sundar
