Problems with Digirig and Kenwood TM-V71A serial access

I have digirig 1.9 RS-232 with the V71 cables. I tested the digirig IAW the suggested vid, and it gave me the loopback values. I rang out the cable. It rang true to the digirig posted schematics 20260303, so it is correct. I can’t connect to the V71 PC port. I then tried another USB-DB9 RS-232 adapter with the Kenwood part, and it worked with chirp and MCP-2A. The digirig specs indicate that it can’t control RTS-CTS, so we are getting what we paid for. It seems that we need a custom cable to use…

Are you using a custom cable? If so, please post specs.
