So I'm setting up a retro gaming computer and I've got a port for a serial mouse. Except it doesn't seem to want to work.
Here's images of the connector and the schematics.
I'm pretty sure I did it correctly, and all the bios settings are changed to "auto", so it should work. Anyone have any other ideas for what might be wrong? I already tried using a different mouse.

(Here's the motherboard manual in case anyone's interested.)

edit: nevermind!
Turns out the cable was broken. I replaced it with a cable from a different case. 😀
