in all the documentations i find in the network, and as well in HCI_UART specification, a DTE is
the HOST of the communication, so it SETS the RTS and check CTS.
Because of the initial nature of the RS232, DTE -> DCE connection that was using a straight connection,
the DTE TX(Output) must still be DCE TX(that must be Input at this DCE "connector" side, and i suppose
swapped inside the device to match UART chip RX).
So, from the above assumptions, i can't understand the image below (imx6 dual / quad reference
manual, page 5163):
In DCE, TX should be an input, as well as RTS. In DTE, TX is an output, and of course RTS also.
The manual shows TX as output in DCE. This seems at my humble opinion, wrong.
What am i missing here ?
