Line Is Breaking - 'Out' Or 'Up' Or None?

Thank you for your response. I really appreciate that.

What about the following, is this acceptable?
At least in casual conversation, can we use this as I sometimes hear people say "You are..." instead of "The line is..."?

You are breaking up. I can hardly hear you.

Incidentally, do "can't hardly" and "can hardly" mean exactly the same thing? If not, are they subtly different?

Hi,
A,The line is breaking, I can hardly hear you......((According to time agreement)).
B,The line is breaking out(start suddenly), I can hardly hear you.......(the meaning is different to the situation)
C,The line is breaking up(become weak), I can hardly hear you.

1- hardly makes the sentence negative so can't is wrong.
2-D,E,F are strange to me,maybe they are some interllingual errors.

Hi,as I explained "HARDLY" makes the sentence mostly(%95) negative.So I can't hardly is wrong.and "you are breaking" can probably be used in casual conversation as you said ,but I think it's just a trasnfer of mother tongue(interlingual error)

Thank you, earlybird, for sharing your thoughts on this. It's becoming clearer to me now with what you've explained.

CJ,

As a native speaker, would you agree with earlybird?
Could you please comment as well on my additional questions earlier?
Is "breaking" without "up" in the given context also acceptable?

Thank you.

I agree that can't hardly and couldn't hardly is wrong.

No.

I thought I had. I wrote, "The other versions you suggested are not right."

Hi,

Your explanation is quite true both about "breaking without up" and the other form of "you are breaking"

Thank you, CJ and earlybird, for your explanations. I now completely understand the topic.
