is there any rs323 standard?

[Meindert Sprang]

And I designed the MC1488 and MC1489 to the RECOMMENDED STANDARD
RS232, which is rarely ever followed now-a-days :-(

How many out there now actually do ±10V signaling ??

I do, using MAX232 and the likes. But this triggered a question you might
know the answer to:
RS-422 defines an A and a B signal and the idle state (logical 1) is defined
as A negative to B. Why is it that EVERY RS-422/485 driver in the world has
it the other way around?

I think only those parts numbered xx1488 and xx1489

I don't know, I never did any 422/485, but I've done a lot of 1553 and
some other MIL-differential the number of which I can't recall, and
LVDS which is yet another breed of weirdness.

I guess OP is saying RS423 or RS422.

and if you google for 'rs standards' you will see
what is in use these days

And if you'd read the content (context) it's clear he does NOT want RS323.

Don, You haven't been following this have you??
There's a reason I posted the smart assed nonsense. My FIRST response
was:

The first result on Google seems very helpful:

no man what I mentioned is RS323 only not RS232.thanks for your reply.

So I then gave him what he wanted: EIA323!
