Serial adapter alternatives
I'm planning to jailbreak my PW2. But, if it is possible, I would like to avoid ordering one of those dedicated usb serial adapters. So could one use other things like a Raspberry Pi (it has some IO connectors) or another Kindle (K3) as serial "adapter" to get into PW2?
Another question: are all the kindle models' serial ports compatible with a same adapter? https://wiki.mobileread.com/wiki/Hard...ex#Serial_Port |

Some cell phone adapters are 1.8v serial adapters. Yes, all use same serial port specs. How did you intend to input things on the K3 that would come out the operator's console serial port? What where you going to do about the things that are already coming out the operator's console serial port? Both sound like a programming nightmare to me. |

Well, I have not thought that all in detail as I have almost no experience in hardware hacking. So as a layperson, I hoped to connect K3 serial pins to PW2 serial pins and work from K3 somehow. Isn't there software tools or libraries (easy to use) to control serial communications?

But all of that is built into the kernel's serial port driver. But the operator's console port is in use by the kernel. And the kernel **must have** a console port. So if you want to use it yourself, you need to first find something else for the kernel to use.

So we need to force the kernel to use a pseudo terminal and release the serial port at runtime. Is it possible?

Just wait for the Kpw2 jailbreak - it might be sooner than you can get that adapter shipped to you. |

I am sure something is possible with the RPi. Although I think is at 3.3v.

That's not super sage advice for the average Joe and Joleen though...
Order the right cable. Best advice. |
