FORScan

What works

ELM327 Module via USB works fine

What does not

It's a liitle bit tricky to make the USB Port available

Workarounds

Using an OBD2 to USB adaptor the interface some settings have to be done to make the serial port to be usable to wine.

1) Connect the adaptor to the USB port. The appropriate linux kernel module should be loaded automatically (i.e.pl2303).

2) Check the tty device emerging
Type into a linux terminal:

ls -al /dev/ttyUSB0

The output should look like
crw-rw---- 1 root dialout 188, 0 27. Jul 10:54 /dev/ttyUSB0

3) Note the group name "dialout". Add the user to this group. Logout/login is necessary to make the group membership effective.

4) Introduce the serial interface to wine as com88:

ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com88

5) Install FORScan

6) Now there is to do some magic. Thanks to Valentin for this hint (http://forscan.org/howto.html). FORScan is unable to detect the COM port until the following registry entries are added (by editing the file ~/.wine/system.reg):

Wine REGISTRY Version 2
#arch=win64

[Hardware\\Devicemap\\Serialcomm] 1517073117

"\\Device\\Serial88"="COM88"

7) choose COM88 in Preferences -> Connection within FORScan

Additional Comments

com1 does not work because wine overwrites com1 to com34 always at start.
