Obdlink SX COM port Problem

[EricTCartman]

hello guys and thanks for the hard work :)

i have a problem with ddt4all and obdlink sx cable it does not connect to the car (laguna 3)
i want to mention that renolink app works just fine without problems but not for ddt4all.
sometimes it would give me permission error could not open port 'COM4': PermissionError(13, 'Access is denied.', None, 5)
and other times it would do this
Initilizing ELM with speed 115200...

Give me your used elm.py file to change.

[benderfuturama]

You need to change baudrate to 115200, renolink is using 1000000.

[KarelSvo]

Simply add the missing baud rates in elm.py ;-)

[benderfuturama]

Will all functions of ddt4all work? Maybe they require 115200?
