RS232 cable?

[Nats-ji]

What kind of circuit do you on your RS232 cable?
I tried this one but I couldn't get it to work.

Sadly the developer will not maintain this driver anymore. :(

That should work, you can check this link where I have an intervalometer software that uses it. Maybe you can test your cable with that software.
