VAG-COM

What works

Everything except a baud rate bug (see below)

What does not

Serial port baud rate would reset to 0 when running a new "Test" or "Select" after a "Test". This makes port unusable

Workarounds

What was not tested

Different adapters (incl. genuine Ross-Tech cables and pure serial), only a noname KKL-USB

Additional Comments

It seems that almost any version of VAG-COM/VCDS would work with the configuration described. I tried VAG-COM 311.2, VAG-COM 409.1 and VCDS-Lite 1.1 - all worked well. Tested using a KKL-USB cable with Serial-to-USB FTDI_FT232R inside. Full device name as seen by OS: /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A400h11D-if00-port0 Device driver: ftdi_sio Do not forget to add a symlink $WINEPREFIX/dosdevices/comN to this device and change permissions (see http://www.winehq.org/docs/wineusr-guide/misc-things-to-configure) Works flawlessly except one issue: if port baud rate is set to 0, the app fails to communicate with "Interface not found" error. When launched from console, a message "err:comm:get_baud_rate unknown speed 1000" is generated by Wine The fix is to use stty and set baud rate to something acceptable, i.e. 9600: stty -F $WINEPREFIX/dosdevices/com1 speed 9600 This is to be repeated after each "Options->Test" and after first "Select". To automate the process, I have created a launcher: #!/bin/bash #VAG-COM launcher for Linux #Does what: # - Launches VAG-COM via Wine # - Specifies COM port baud rate, if set to zero (fixes an "Interface not found" bug") # - If necessary, applies fix to VAG-COM 409.1 (fake registered version) # - Repeats on specified interval # Copyright (c) Alexey Antipov 2011.
