How does Milyn feel about the Com port on the subject. The modem is connected using the Kondratiev scheme.
With respect, SP/PoS.

KS> How milyn treats the Com port on the subject. The modem is connected according to the diagram
And "milun", is it me - E. Milun? Then I don’t relate at all, the com-port is on its own, and I’m on my own. Or is it my terminal? Then she just
uses it... :))
But seriously, I somehow didn’t understand your question. Have you stumbled upon a modem with PnP? Then, nothing can be done here. It is not known why, but
these modems stop generating interrupts after re-initializing the com port. And in general, either they have a somewhat strange IRQ signal, or they just have a weak data bus, but even in Melon (not to mention the S-Terminal)
they often produce all sorts of garbage instead of meaningful information.
Good luck! Evgeny.

Because it’s a program, and I made a mistake in writing the name (as many as 2), because
it’s similar in spelling. but in fact - Melon.

Of course you can.

And I have a modem with PnP, but in Melon everything is OK, it doesn’t use NMI in general.
Well, S-Terminal freezes, sometimes it doesn’t - but if you press something, it will appear on the screen
after 0.5-2.0 seconds, and when you change the port speed, it freezes
completely :( Although in Melon it’s normal... Kondratieff scheme...

Once, 27 Oct 98, Konstantin Samoylov was chatting with Evgeny Milun
about {Modem}:
KS> No, just if there is a difference between what Com is set

8-[ ] Of course there is!!! Which comport is displayed on the subject,
it must be plugged into such a port and the same port must be set
in the terminal.

Good bye ! ... Pintium is a hot mess...

That’s why I asked. I already said once - some of us call my S-Terminal as “milun”, precisely because of its consonance with Melon. :))
DT> 8-[ ] Of course there is!!! What kind of computer is displayed on the subject,

How is that? Let's plug it into Com 4?!!? I can’t imagine this.

Where in Melon is the Com port set for a modem connected using the
Kondratiev scheme?
With respect, SP/PoS.
He tried to bus the address on the momed and upr. signals through a buffer
or schmidt triggers to skip ?
W!7h Be$7 W!$he$, FK0.
Well, this is for those who have a subject in SMUC
KS> Where in Melon is the Com port set for a modem connected using the Kondratiev
KS> scheme?
Nowhere. Set the modem to Com1. Or Com2 - but then switch a few wires on the
connector.
It is assumed: if the modem is plugged into a Kondratiev circuit, it is set to
com1 irq4.; The modem is not PnP, the best is USR 93/94.
Happy, Konstantin. It was nice talking.
KIR.
KS> I can imagine.
It depends on how you have the connection diagram. modem is set. For example, when the modem was connected to the MK circuit, and it supports com1, I had a problem with
installing a com port on the modem itself, i.e. There was no dock and I selected the port, and
I only selected com2. I had to change the port address in the scheme and transfer irq, in
in accordance with the writing standard.

I have USR with PnP too. In Melon everything is OK too,
though I didn’t really use it, but I tried to connect. If I lock the
port
to 38400 - it hangs, the author warned. ZXNews-15, it seems) didn’t
work with it at all until I shortened the IRQ with a capacitance. Maybe you could try to reduce it further?
All the best.
Roman.
KF> We did not try the address bus on the momed and control. Should I pass signals through buffers
KF> or Schmidt triggers?
Personally, I don’t. :) Everything works for me anyway. But someone else, it seems, tried, and, it seems, the garbage became in order, but with interruptions - no.
But, I can’t say for sure.
EP> Well, this is for those who have a subject in SMUC
So I wrote in Russian that the modem is connected according to the Kondratiev scheme...
KS>> Where in Melon is the Com port set for a modem connected according to

EP> Nowhere. Set the modem to Com1. Or Com2 - but then cross several wires on the

And if Com4 and IRQ3 are installed on the modem, then which wires need to be crossed
?
With respect, SP/PoS.

KC> gg.
There is a problem here, the fact is that the modem only installs on COM4 IRQ3 or 4
What to do with this?
Sincerely SP/PoS.
EP> Well, this is for those who have a subject in SMUC
Yeah, everything would be fine, but my modem started working in SMUC only when
I set COM2 on the modem, and in Melon it’s also COM2, but it doesn’t
react at all to com1. It is possible that my modem is buggy, although in the normal mode it responds normally to
som1.

But it works on a PC... Maybe P'n'P has a different port operation algorithm?

KS> IRQ3 or 4 What to do with this?
Then you need to redo the circuit a little. I don't know how to supposedly bridge a few wires. Perhaps someone present here will
tell you.
KS> Where in Melon is the Com port set for a modem connected using the
KS> Kondratiev scheme?
For the Kondratiev scheme, you need to set COM1 and IRQ4 on the modem.
Good luck.
Roman.
Apparently, only A8, A9 and A10 will be enough...
All the best.

and you need to throw on the slot, the one that is isa'shny, A27 and A23 to the ground, and
the irq signal, which comes from the 3rd leg LH1 - to B25 (was on B24)
And that's it, it should work - I'm telling you this as a doctor ;-)))
if, of course, the modem is working ;-)
With best wishes, Dmitry.
KS> on COM4 IRQ3 or 4

The answer flew away ;-))))
Well, at least tell me, for the sake of decency, whether it will work or not.... ;-)
Although theoretically it should. And I practically had it, only on com3.
With best wishes, Dmitry.
To everyone who answered and explained about the subject, *Much THANK YOU*, now everything seems to be working.
With respect, SP/PoS.

Exactly. As far as I remember now - A8, A9 and A10.

├┤i Roman & Konstantin !
RM> For the Kondratieff circuit, you need to install COM1 and IRQ4 on the modem.
Why bother with coms and irqs? Here I have irq_5.
And that’s not the point - it’s easier to transfer the wires on an adapter
(Kondratieff circuit) than to think about which com or irq.
