Hello,

No. The RTDM Serial driver communicates with the UART of the PC. For a
usb-serial converter you would need a USB real-time stack (which is
available with usb4rt). And not all usb-serial converters are the same,
I know at least two types: ftdi_sio and pl2303 which seems to be most
common. In linux/drivers/usb/serial there are quite more. So you need a
driver for each converter based on usb4rt.
I think it's easier to buy a serial PCI card. :)
Regards,
Bernhard
