dot Net Application use serial Port over socat (TCP/IP)

[hulk0815]

Hello,

i use an dotNet App, with socat (ttyUSB0 oder TCP/IP). The App cannot open the Com Connection. I mapped it to a File called /home/username/.com3 in "wine regedit Ports".
But it doesen't work.

Have anyone a Solution for me?

The dotnet App use System.IO.Ports, how can i import these?

Make sure the user has the necessary permissions to use ttyUSB0. Often, the user must be a member of the dialout group.

I mapped it to a File called /home/username/.com3 in "wine regedit Ports".

As a check, what is the output of:

Code: Select all

wine reg query 'HKEY_LOCAL_MACHINE\Software\Wine\Ports' /s
# and
ls -asl ~/.wine/dosdevices

Morning,

1. wine reg query 'HKEY_LOCAL_MACHINE\Software\Wine\Ports' /s
HKEY_LOCAL_MACHINE\Software\Wine\Ports
COM3 REG_SZ /home/vdi1/.com3

2. ls -asl ~/.wine/dosdevices
lrwxrwxrwx 1 vdi1 vdi1 10 13. Sep 11:53 c: -> ../drive_c
0 lrwxrwxrwx 1 vdi1 vdi1 10 28. Sep 07:52 com1 -> /dev/ttyS0
0 lrwxrwxrwx 1 vdi1 vdi1 10 28. Sep 07:52 com2 -> /dev/ttyS1
0 lrwxrwxrwx 1 vdi1 vdi1 17 28. Sep 07:52 com3 -> /home/vdi1/.com3

This is the error Message from the dotnet App.

Have you tried installing the Windows .Net Framework with winetricks?

Code: Select all

winetricks -q dotnet48

Hello,

sure, the Application runs, but when he contact the Com port comes the error message.

When i use putty.exe (for Windows) under wine, and connect to the Comport runs normaly.

I think the com port mapping over socat was ok.

The dotnet app found the COM port, but when it try to .open then comes the error.

Anyone an Tip or Solution for me?

[jkfloris]

Do you have a (legal) link to the program?

[hulk0815]

Hi,

yes i have an test for you, i upload these in a few Days.

Thanks.

HI,

here is the Link to download the dotNet TestApp.

The Link is activated to Sunday.

Thank you for the test application.
I think the problem is in "socat". Could you check this with setserial?
Does this return a valid value:

Code: Select all

setserial -g /home/vdi1/.com3

Additionally, you can enable the "comm" debug channel in wine to see what is going wrong.

Code: Select all

WINEDEBUG="+comm" wine SpikeComport.exe

Good Morning,

the result from setserial is: Cannot get serial info: Inappropriate ioctl for device

Have you an idea for socat or anything else?

[jkfloris]

I was afraid this would happen. "System.IO.Ports" uses the same way as "setserial" to use the COM port, which unfortunately does not work via socat.
If the device is connected via USB, you can try to remove socat and make /dev/ttyUSB0 point directly to a COM port in Wine. (In the test application, this had to be COM8).

Unfortunately, I don't know any other solution than socat for the TCP/IP to serial connection.

Ok, i woud like to use Linux TS (xrdp), and there is no com port mapping included.
