Debian currently does not build its Linux kernel with CONFIG_USB_SERIAL_CONSOLE=y, which is required for this feature to work.
The corresponding bug report is https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=868352
After building my own kernel with CONFIG_USB_SERIAL_CONSOLE=y (see https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#s-...

Using “screen” as terminal emulator under UNIX/LINUX
To start a session, type “screen” followed by the serial device name and baud rate:
Unix prompt> screen /dev/ttyUSB0 9600
To get to ...
echo AT | socat - /dev/ttyUSB1,crnl
This sends an AT command, returns the output and finally exits.
The linux command can be used for several AT commands in script with a delay of 1 second after each command.

serial.serialutil.SerialException: read failed: device reports readiness to read but returned no data (device disconnected or multiple access on port?)
I went up to 20 before it stopped giving an error, started at ...
Serial is a very basic communications protocol and is operating system agnostic. You should be able to use it to communicate between different operating systems, but you have to get all the details on both ends correct.
The bios POST is probably showing because the bios has serial console enabled. However, once the operating system boots, the operating ...
I have configured DB-9 pins as full duplex RS485 as below
And do you also have hardware that works as RS485 with a differential signal, or do you have a normal serial port? Because normal serial port hardware doesn't produce RS485 signals, and your logic analyzer output very much looks like a normal serial port.
So you either need to buy RS485 hardware, you ...
In my research you need to add a string entry under HKEY_LOCAL_MACHINE\Software\Wine\Ports with a key of COM1 and a value of /dev/ttyUSB0 (or /dev/ttyACM0 if it is the case) to access the USB port from wine.
This is saved in .wine/system.reg as
