Which solution did you try? What doesn't work?

There is a special component for the WJ200:

Though that is a very rubbish documentation page!

Looking through the source code:
github.com/LinuxCNC/linuxcnc/blob/master...0_vfd/wj200_vfd.comp

The component would be loaded with

loadusr -W wj200_vfd --baud 115200 --parity 0 --databits 8 --stopbits 1 --device /dev/ttyUSB0

for example.

Note that the driver is loaded with wj200_vfd but the pin names follow the HAL convention and use wj200-vfd
