[Coco] raspberry pi 3 model b to coco serial cable

[camillus gmail]

HI,

I I remember correctly the coco only has 4 line serial, TX RX and CD ( Carrier Detect ) and ground. You need to cross wire the TX, RX, and use an signal to CD, I think when its low the coco send data and when hi coco stops sending. A coco printer uses his Busy signal to CD I think. 

Read the cocomanual for sure, because this is 35 years ago I played with coco on serial ports.

I need to make a serial cable to connect my coco to my raspberry pi.

I see the mini uart on the pi is connected to 8 and 10 for tx and rx.

Anybody have a pinout to help make a cable?
