    E34 DIS V44 Help

    Ok, Im going to try to explain the problem as best as possible, but Im sure that there will be little things that I miss so feel free to poke and prod. ;)

    Problem = I can't get the car and computer on speaking terms

    Modules Im trying to talk to:
    -GM to try to diagnose a problem with the rear window switches (the rear windows only work when using the master switch in center console, regardless of child-lock button).
    -IHKR controller to code for the AUC Sensor and control module
    -Cruise Control Module to see why it is not working (Stalk, actuator, and most of loom are perfect [where accessable on loom])
    -ECU because... honestly, why not? It's super useful.

    My setup:
    -Panasonic Toughbook CF-29 dedicated for use as a MODiC and nothing else
    -Windows XP SP3 32bit
    -Tiny ADS connected to HARDWARE serial
    -EasyDIS V44 install with VMware Workstation 6.04
    -INPA 5.00
    -EDIABAS V6.4.7 according to C:\EDIABAS Version.txt file (dont quite know what to make of this as I did the 6.4.3 rollback/replacement thing)
    -E34 525i 5-speed 11/27/95 build date (DME 3.3.1 for M50B25TU)
    -Original car phone and assosiated trunk module removed years ago by dad, replacement interface box from E32 installed in center console to restore function of BC button with check control display.
    -C43 radio with I bus trace cut to prevent interference with E34 LAC-DAC lines (Not quite a plug and play like everyone says! Caused the famous ESD Regelt warning [and MANY others] to display even with a perfect CCM.)

    Symptoms:
    -DIS and INPA both boot with no warnings
    -Good battery and ignition lights in INPA
    -ABS light in cluster briefly flashes when trying to talk to that module in INPA
    -Check control screen text will flicker during all attempts to communicate with any modules watch here: https://youtu.be/MFvLwQK6BK8
    -ECU communication attempt throws IFH-0010 (data transmission disturbed) and "DM331K20 not found"
    -Other errors: SYS-0012, IFH-0009, SYS-0013 (for Cruise control)
    -DIS just throws the data transmission disturbed
    -ifhsrv32 and Ediabas server are running during all operations
    -Buffer settings for COM1 are set to max. There are no options for latency settings (unless they are accessed through the windows registry)

    I feel like Im so close, but It's like the latency is wrong or something (not sure this is possible with hardware serial, but Im open to being wrong)

    Am I missing something small? Or Big and obvious?

    Thanks,
    Singing6

    Ok, so I changed the receive buffer from 16 (max) to 14. Now I can talk to late 95 E34's but i still get lots of errors with the 525i. When i played with a 540i, everything was perfect, same settings with the 525i and I get super slow refresh on analog values for DME 3.3.1. Any Ideas as to what I need to check?

    I'm still trying to get INPA to show the battery and ignition signals. My adapter from One Stop Electronics shows the ads and ignition led turn on but INPA don't want to show and attempting to communicate gives a IFH-0010 error.

    Okay I learned today that you must have a straight through db9/serial cable. Null modem cables will not work. INPA is talking to the car but I'm getting the SYS-0012 identification error when attempting to talk to most components including the ecu.
