smaller HP 82166A with 32-pin connector

[KimH]

Yes, I have 2 times 82166A mounted on the board in each their own loop with a 71B each - one TALK and the other LISTEN.

What I wanted was to see the sequence which was sent on one device re-appear on the other device, one by one. This would tell me that the loop was working and that I had understood some of the basics..

I believe I have done what you suggest but clearly I will try again.

Maybe I am dealing with a mundane challenge - one or both the modules are not working as expected.

I will drop a note here once I know more

Thanks for your suggestions and for your time!

Quote:Are you using 2 HP-71B, one on each side? Otherwise you must address the 2 converters with their own addresses.

That sounds quite complicate to just send bytes from one converter to the other.
You may start using the default control register setting and just do
OUTPUT 1;A$ on one side and ENTER 2;B$ on the other side.
Be sure to restore the default ENDLINE condition! otherwise it will not work.

To be more specific, I believe your test code above may hang at line 20 because the ENTER statement doesn't find a string terminator (since you disabled it with ENDLINE "").
