SamyGO

You could ask your neighbor or co-worker for soldering three wires with two connectors together
Sure you can buy it. But i think it is overpriced here

I dreamed a SamyGO Market Place for selling ExLink cables under SamyGO brand

I found an online-shop here in Germany which sells such a cable "PICAXE-Programmierkabel seriell"
(Serial cable with 3,5mm stereo)

There is also a USB programming cable. Could this be working too?
(USB cable with 3,5mm stereo)

Converter from USB to Serial is integrated into the cable.

Yes, i think it is good for B series. Cool. And price is awesome

Ok.

Does your answer refer to 1.) the serial- or 2.) USB-cable ?

I wonder, if the USB-cable will work.

My answer refers to the first.
The second cable should be ok to be used as ExLink too, but it is a bit expensive, so, not so awesome

Just a bit?
I can send you a BlueTooth one for that price!

I bought the AXE027 Cable and this one seems not working.
I get some pages of mixed chars but I cannot read something.
I'm not able to break the output and go to console.

1. B series doesn`t need cable with built in ttl converter
2. miched chars can be because of wrong connection settings
3. you can`t break all and get to console, because your:
a) console is locked
b) firmware is restricted and here is not possible to unlock console, need to downgrade firmware first
c) tv is ci+, no possible to send ctrl +c , shell input is limited
d) all other reasons, first of all - non working cable, bad pinout and so on.

You gave poor info about your television hardware. Btw, i think for B series exlink here is a lot of information, no need to invent the wheel. Just check wiki.
