I have no idea to the specifics of what you are asking, or the context, or anything.
But I thought I'd just point out that a real DZ11 actually only have 8 lines, and there are probably a few bitfields in the registers of that device which are limited to just identifying 8 lines as well.
However, if you are running simh, and want more than 8 lines, there is really nothing preventing you from attaching multiple virtual DZ11s to your machine...

Have you tried asking on the SimH mailing list? (I haven't seen the question
raised there.)
It would be helpful if, when you ask your question you include the output of
"show config", and possibly the DZ11 section of F.MAC and S.MAC as well.

Uh... That will be very *not* DZ11 compatible... One DZ11 can only support 8 lines. You could be creative, I guess, and do an extension of the DZ11, which would support more lines. There is one free bit after the line field in the registers, which would allow you to easily extend it to 16 lines. But beyond that, you need to become more creative.
However, all this is moot unless you also change the device drivers for the OS, since they too will mask out the line number and only allow for eight lines today.
All this is per controller. Of course you can have several controllers, which allows you to get many many lines total on your system.
But that also means you need to know what to set the CSR address to, and configure your OS to actually handle all the controllers...

Are you saying that you set up four DZ11 with 8 lines each, or one DZ11 with 32 lines?

Sounds like one DZ11 to me.
> what am I doing wrong?
Don't know. Although your description here seems to be confused. Are you sure what you are doing, what can be done, and what the expected result would be?

Ah! Thanks Don. That explains it all for me. And it is sane.
So, drforbin needs to define all the DZ11s in his config on the PDP-10 side for it to work. If he defines only one, then yes, of course he will only see 8 lines.

But what IS a DZ11. Is it a PC board with ICs on it?
If so, then I would say zero DZ11 in all cases.
Now, say someone made a PC board with 32 ports that took
up the same CSR ports as four regular DZ11s, and the same
interrupt vectors as four of them, and even more called the
board a DZ11. (With a little luck, someone forgot to trademark
DZ11, and they could sell theirs.)
Even more, since it is all virtual, you can now write an emulation
for this board.
Physical devices are easy to count, virtual ones not so easy.
If you partition a disk drive, then mount the partitions under
Windows or DOS then each has a drive letter, and each, as seen
by DOS, a disk drive. But still, physically there is only one.
I little google search seems to indicate that there are physical
cards implmenting more than 8 ports.

??? We are talking about something under simh here...

This don't make sense. The bus on a PC don't work the same way as a Unibus anyway.

Hmmm? But we are talking about a DZ11 under simh. What actual hardware you might be running on is of less importance. That is something for the host OS to worry about.
> Physical devices are easy to count, virtual ones not so easy.
I don't totally agree. Virtual (as in simulated ones) are just as easy to count.

Yes. Same thing can be done with some controllers on a PDP-11. :-)

There are plenty of cards that have more than 8 serial ports. Not sure what that proves.
