ok, so
UFCR_DCEDTEis set andUCR3_DSRcontrols the DTR output as intended. What is connected to the respective pin?MX6QDL_PAD_EIM_D25__UART1_DSR_BI think is the one.

It's routed out to Apalis SoM pin 120, which is then connected via 22R resistor and through SN65C3243DBR RS-232 line driver to header which I use as debug/serial console.
Then I guess the problem is that the rs232-partner asserts the imx6's DSR in reply to the imx6 asserting DTR?
Yes, that's correct.
