How does Direwolf control the behavior of DTR ?

[xiaofami]

I'm using this interface with a USB soundcard to connect FT-8900R to a TV Box running Manjaro ARM and Direwolf (Version:1.7, built from source )for packet radio :

Currently I'm testing without radio connected. I notice that the DTR LED is always on after direwolf is up and running. I'm wondering if it is the expected behavior as the manual of U5-Link described :

RTS LED: Blink when PTT triggered (Working as expected)
DTR LED: Blink when CW triggered, synchronized with dot or line (Not working as expected, always on when direwolf running)
PW LED: ALways on after USB cable is connected (Working as expected)
REM LED: Blink when changing radio freq with CAT (Could not verify)

I've contact with the U5-Link inventor and he claimed it as "software wrong setting" though I seriously doubt if he has ever played with direwolf. Further more, the manual suggests these setting:

RTS=PTT
DTR=CW
CTS=SQL

so what is supposed to set in direwolf.conf to make DTR behave as expected ?

I only made minimal change to default direwolf and below is what I've changed:

ADEVICE  plughw:0,0
MYCALL BH2VJW
PTT /dev/ttyUSB0 RTS
