Check your connector. Those Rj12s can get squidgy with enough fussing
about.

Really odd that yesterday evening it worked and I got valid ocean
temperature values.
Back to checking wiring.

Definitely sounds like the 1-Wire bus is getting shorted out.

That's encouraging.

Is that with the correct connections or the original wrong ones?
Correct the wiring, if it is wrong, and try again. Check the manual
for the
I must have something else wrong. When I connect the DS18B20 without a
resistor the MS-TV disappears.
Odd that it worked last night - with a 5K resistor.
I do not know electronics.

Bingo! I think.
Adding a short sleep right *before* turning on the break seems to have
solved it. My guess, the 'b' was still pending in the FTDI chip's
buffer, and when sending the break too early, it never had a chance to
reach the Link chip.

I didn't read your message carefully.
"Are you using a dedicated onewire host adapter chip or just a simple
GPIO pin? For the latter you have to connect the pullup to 3.3V, not 5V."
I am connecting from the DS18B20 to cat6 to the MS-TV.
I am not using the GPIO. Don't know how. I have other sensors

I think 3 wire, but don't know. That is:

If this is 3 wire, what is 2 wire?

In your initial post you wrote "I have a Raspberry Pi with LinkUSB and a
MS-TV reading DC voltage."
If you have a LinkUSB, you don't connect your 1-Wire devices to a GPIO
pin, right? The LinkUSB should not require any pullup at all.

It did not work without the resistor.
I thought to look at Adafruit product information:
https://www.adafruit.com/products/381
"We toss in a 4.7k resistor, which is required as a pullup from the DATA to
VCC line when using the sensor."
Yesterday evening it worked with the 5K resistor. (Actually 5

Where did you read that? Did you try without the resistor?

I have a Raspberry Pi with LinkUSB and a MS-TV reading DC voltage. This
works.
Yesterday I added an Adafruit DS18B20 waterproof temperature sensor and it
worked for a while.
This morning neither the MS-TV nor the DS18B20 are seen by owfs.
If I remove the DS18B20 the MS-TV reappears.
