[Prepar3D v5 HF2 does not quit when COM ports used for VRInsight]

It works now but I don't why.

I did some analysis with Process Monitor from Sysinternals and tried a workaround with Virtual Serial Ports Emulator (accessing the buggy FTDI USB COM port with VSE between...). I changed a lot of settings and set them back to the original value afterwards. So I would say, I've the same setup as before, but it works now. Prepar3d closes now all processes after a couple of seconds.

One of my last manipulations was to deactivate the COM port device in the device manager and activate it again. I updated the FTDI driver earlier before but without success as well. Maybe the deactivation / actviation cleaned up some internals.

However - it's all guesswork now since I can't reproduce the bad behavior anmymore.

I'm happy with the working system now. Maybe I'll have now a look on LINDA again.

 

Pete, thank you for the support!

 

Best wishes,

Rainer

Ouch. So the adapter is built into the device. Shame.

In my oppinion the adapter is build into the cable or into the USB plug. I know such cables from my job (for example this one). I think so because the sim hangs even without switching the VRInsight combo panel on. It's enaugh to plug it into the PC. And since the cable is powered anyway the virtual COM port is visible in my system and FSUIPC can open it with the panel switched off.

you aren't connecting to a USB-3 port (blue coloured) on the PC are you? If so, don't. Many older USB devices don't work well on USB3 ports.

I'm connecting to a red one 🙂 USB 3.2. Ok, thanks for this hint. I'll try it.

As the support developer I would recommend you investigate LINDA 3.2.6 which works with all VRI combo MCP panels and P3Dv5.

As I stated earlier I've already tried LINDA. This is a different story. For the given problem it doesn't matter if SerialFP2 or LINDA is running or not. Thanks for the suggestion anyway.

Could you please tell me exactly how your VRI device is connected to the PC?  Is is a built-in COM port board (the recommended way) or a line adapter COM to USB? If the latter can you tell me the make please?

I use the first version of VRInsight's MCP combo panel. The only option to connect this device to the PC is the attached USB cable.

It installs as "USB Serial Port (COM3)" and uses FTDI drivers. So it seems to be a cheap FTDI USB to COM solution.
FTDI driver date 09.03.2016 version 2.12.16.0

Anyway, one of the workarounds for VRI devices we devised which has worked for others is:

VRIDisableCMDRST=Yes

in the [General] section of the FSUIPC6.INI file (if the parameter is already there, make sure it is set you 'Yes'. Else add the line. This will simply not try to reset the device when you finish.

Unfortunately this doesn't help. The COM Port and its handling process does not quit. Same without this option.

WhatIsHang finds exactly the process I found in the task-manager windows Immediatly after Prepar3D shuts down the process "Prepar3D.exe" shows up in the WhatIsHang window.

This is the upper part of the details view for this process. I left the memory data aside...

[Prepar3D v5 HF2 does not quit when COM ports used for VRInsight]

Yes, this is the end of the log.

This was the first time I'm trying to use the VRInsight facility of FSUIPC. So the answer is no, I haven't had this working before.

I have tried LINDA but it was a disaster for me (the response time to button presses was 1 second and above). Then I removed every LINDA software part I was aware - for example the LUA script start commands in the FSUIPC ini file.

Thanks,

Rainer

[Prepar3D v5 HF2 does not quit when COM ports used for VRInsight]

Hello Pete,
folks,

 

My problem is, that when I'm using the FSUIPC feature for VRInsight serial devices the Prepar3D v5  flight sim does not quit all processes when I'm leaving it with CTRL+C or by the "Exit..." menu function.

I have this entry in the FSUIPC ini:

[VRInsight]
1=COM3,COM12

Everything works great with it besides the mentioned problem. All is set up according to the FSUIPC manual including the Virtual Serial Ports Emulator software. When I start the sim (Prepar3D v5 Hotfix 2) the VRInsight software SerialFP2 is starting and my MCP panel is functional.

After the flight when I quit the sim the windows are all closing and I'm back to desktop. But a background process is left -> "Prepar3D exe" using about 2 gigs of main memory. It's visible with the windows task-manager. Another evidence of the running process is the microphone icon in the system tray which pops up when an application accesses the microphone, in this case Prepar3D v5. It remains in the tray after quitting the sim. When I shut down the background task by the task-manager function the microphon icon is removed.

Commenting out or removing the [VRInsight] entry in the FSUIPC ini solves the problem, no background process remains in the main memory after quitting the sim. This is 100% reproducible for me. It doesn't matter whether SerialFP2 or Virtual Serial Ports Emulator were started.
