Windows 2000 COM1-port user driver

I am looking for a virtual solution for a Windows 2000 application, that are using a user written WDM-driver installed on COM1.
I have tried VmWare Workstation 15.5, VmWare Player 7.1.0 and ESXi 7.1 with 'pass through' and it works regarding sending and receiving data, but the driver also manages RTS to change direction of data on a RS232 to RS485 converter. This 'signaling' with RTS does not haven using VmWare.
Does ProxMox VE support user-written COM-port drivers regarding hardware handshake in a user-written WDM-driver.
If yes, how to configure it ??

Best regards

passthrough a pcie full card can work. if pcie card has a driver compatible with Windows 2000.
even passthrough an usb-serial converter (or directly the usb port) can work, if driver is compatible with Windows 2000.
perhaps qemu can passthrough the device with correct I/O port address (for pcie. I don't know for an usb if it can be emulated) with args options or manual qemu command line.
it's an advanced virtual hw configuration, it's more tied to qemu side not really Proxmox.
