Building a Minitor 5 programming cable

I'd like to try building my own USB cable to program my Min 5 and I'm wondering if it's a simple USB cable with an RJ-11 on the end or is there more to it? If it's a simple one, does someone have a pinout for building one?

I've seen them on ebay but wanted to try my hand at building one instead of putting out the $$. I have the UPI already, it's just a PITA to use it all and would like to ditch it for a simple cable.

Thanks all.

Nope, you can't just use a USB cable. It has to contain a circuit and chip that converts USB to TTL. A tiny bit of internet searching yields all the info you could hope to find about this. It is incredibly well documented at this point in time.
