I don't own this adapter, and I have not tried to make it, so I can't help on this subject, but maybe you will find some useful information in this document.

If it helps, I just found another DIY adapter on a Japanese web site (Google translate to the rescue). This one is based on the ADM232A and uses a standard RS232 male 9 pin connector, not USB:

Here is some interesting info on the G850V UART registers (in Japanese):

Disclaimer: I have not tried this DIY RS232 level converter/adapter.
