Just one question:
Receiving with hardware handshake works without PDC?

I don't know...I haven't tried. These patches shouldn't change anything
though.

I refer to this part of documentation:

"The USART behavior when hardware handshaking is enabled is the same as the behavior in
standard synchronous or asynchronous mode, except that the receiver drives the RTS pin as
described below and the level on the CTS pin modifies the behavior of the transmitter as
described below. Using this mode requires using the PDC channel for reception. The transmitter
can handle hardware handshaking in any case."
