Troubleshooting

If there is a bug with the functionality of our software, do the following:

On the computer where Serial Port Splitter is installed, download the enable_logs.reg file and apply it.
Alternatively, launch regedit, find the LogLevel REG_DWORD value in the following registry locations and set it to 3:
```
32-bit:
HKEY_LOCAL_MACHINE\SOFTWARE\FabulaTech\Serial Port Splitter 
```
```
64-bit:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\FabulaTech\Serial Port Splitter
```
Restart the service: Serial Port Splitter service (ftspssrv.exe) or reboot your PC.
(Press Win+R, type services.msc, right-click the required service and select Restart. Administrator privileges are required to perform this operation.)

Reproduce the issue you encountered 2-3 times. Remember local time when the problem was reproduced.

After you enable logging and restart the services, log files will be created in the following location:
C:\ProgramData\FabulaTech\

Add this folder to archive (right-click, then point to Send to and select Compressed (zipped) folder).

Send compressed logs to us (). Specify local time when the problem was reproduced and both local and remote user names who was involved in the reproducing.

Disable logging (in order to improve the performance of your PC).

On the computer where Serial Port Splitter is installed, download the disable_logs.reg file and apply it.
Alternatively, you can launch regedit, find the LogLevel REG_DWORD value in the following registry locations and set it to 0:
```
32-bit:
HKEY_LOCAL_MACHINE\SOFTWARE\FabulaTech\Serial Port Splitter 
```
```
64-bit:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\FabulaTech\Serial Port Splitter
```
Restart the service: Serial Port Splitter service (ftspssrv.exe) or reboot your PC.
(Press Win+R, type services.msc, right-click the required service and select Restart. Administrator privileges are required to perform this operation.)

If the process crashes, do the following:

Enable dump creation.

This feature is not enabled by default. Enabling the feature requires administrator privileges.

To enable Crash Dump, download the enable_dump.reg file and apply it.
Alternatively, enable and configure this feature using the following registry values under the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps key:
```
- value: DumpFolder, type: REG_EXPAND_SZ, data: %LOCALAPPDATA%\CrashDumps
- value: DumpType,   type: REG_DWORD,     data: 2
```
Reboot your PC.

Reproduce the issue you encountered 2-3 times. Remember local time when the problem was reproduced.

Collect dump file.

Location of crash dumps:

1. Applications:

%LOCALAPPDATA%\CrashDumps

2. System services:

%WINDIR%\System32\Config\SystemProfile\AppData\Local\CrashDumps

Or, in case of 32-bit service on Windows 64-bit OS:
%WINDIR%\SysWOW64\Config\SystemProfile\AppData\Local\CrashDumps

3. Local and Network services:

%WINDIR%\ServiceProfiles\LocalService\AppData\Local\CrashDumps
%WINDIR%\ServiceProfiles\NetworkService\AppData\Local\CrashDumps

If not configured properly:

C:\ProgramData\Microsoft\Windows\WER\ReportQueue\

Add the crash dump to archive (right-click, then point to Send to and select Compressed (zipped) folder).

Send compressed dump to us (). Specify local time when the problem was reproduced and both local and remote user names who was involved in the reproducing.

If there is a BSOD caused by our software, do the following:
