I have a dumb question. I have an older laptop here that I use
everyday that I purchased in 2010 and is running version 1809 of
Windows 10 Pro. It is a business laptop and has a rs232 interface
(even has a modem :-)). Why don't you shop for an older laptop with
rs232? The reason I use this older laptop is I like the keyboard
better than the new keyboards. Now it moves past my ability because
he would have to link the older computer to his new computers over
the network so he could print through it. I would assume the older
laptop could be setup as a print server.

That idea went through my mind several times. The data
going to the CNC machine from the laptop runs a $$$$ CAD
program that is a power hog. The customer spend 5,000 U$D
on the new laptop.

If I don't get the cable adapter working, using an old
laptop as a server is a good idea. But make sure it
has a USB port free to run a "sneaker" net over to
it. And leave the old laptop sitting on the CNC
machine's utility table.

How about the cheapest small computer you can find that has the power (I am
assuming computation power) that can run the program and you can stick a
rs232 card in? This would be less costly than a laptop.

He already has the laptop. And since the laptop and the iMac
are the ones generating the code, he wants to use what he has.

You can still get motherboards with com ports built in. The Asus
Q270M-C/CSM has two com headers for instance and that was the first
board I looked at.


Supermicro has them too, but just headers. You have to
buy your own bracket. Some Lenovo desktops come with
a single db9 on the back still

My new Asus z390 prime MB has one com header on it.

Don't network devices still use serial ports too? Or is that finally moved on?

Serial protocol? Yes, that's still common. DB9 serial ports? I haven't
seen one in at least a decade, possibly longer. Instead, Cisco decided
to change the DB9 port on their equipment to an RJ45 port so that any
Ethernet cable can be used, as long as you have the proper adapter on
the far end to adapt the Ethernet connector to a standard DB9 connector.
Since then, the other equipment vendors appear to have followed Cisco's
lead, as is often the case.

That brings this thread full circle, because now you have to find a way
to plug the DB9 connector into your PC. That's where the USB-to-DB9
adapters come in, if your PC no longer has a native DB9 serial port.

I meant to include a link to one of those Cisco serial cables, showing
the DB9 on one end and the RJ45 on the other end. The RJ45 end plugs
into the equipment; the DB9 end plugs into a serial port on the PC,
whether directly or via an adapter.

Some Apple protocol did that.

At the time, the CPU load was intense enough, the CPU stayed
in a loop while transferring data. Once a packet was sent, the
CPU could go back to editing your Word document.

https://en.wikipedia.org/wiki/LocalTalk

"the Mac was given expensive RS-422 capable serial ports.

The ports were driven by the Zilog SCC, which could serve
as either a standard UART or handle the much more complicated
HDLC protocol

yielded the fastest rate available, namely 230.4 kbit/s"

So that was an example of trying to build a network for "cheap".
Cheap and not very cheerful.

We determined empirically back in those times, that

"1Mbit/sec is all we will ever need"

with a smirk on our faces. For that was the rate
at which users stopped complaining :-) Naturally,
if we could offer more than that, it put a smile
on their faces. People would have killed back
then, for 10Mbit/sec Ethernet.

People today are spoiled by excess. A person
with a 10Mbit/sec Ethernet connection would tell
you they "felt like they were in prison". Think how
long it would take to transfer a Macrium backup
to your NAS, on something like that.

I just wired my house with Cat6a so I can (someday) have 10Gbit
transfers. At work we have 40Gbit connections. How did we ever get by
with less?

What kinda wire does the 40Gbit use ? :-)

Monster brand cables ?

I see a kind of wire here that seems long enough
for your computer room. Not enough length for
a whole house though. There is a 5 meter version.
Wikipedia mentions the wire is twinax.

https://www.amazon.com/10Gtek-QSFP-H.../dp/B00SIW0T9O

And there's a Cat 8.

https://en.wikipedia.org/wiki/Cat.8#Category_8

"It is defined up 2000 MHz and only for distances
from 30 m to 36 m depending on the patch cords used."

I'm sure that'll be cheap. In a picture here, there are
four pairs in the wire, and they're wrapped in a mylar foil.
So that's your "twinax". And at a dollar a foot, what's
not to like ?

https://www.amazon.com/Buhbo-Etherne.../dp/B07J16VWT8

"Fast Superior Perfomance: Supports a high bandwidth up to
2GHz (2000MHz) and transmits
data speeds of 25/40Gbps. "

For console ports? yes, they may be disguised as 'RJ45' connectors, or a
USB port that has an embedded USB-RS232 chip, but they're still serial
consoles, and life-savers they can be too ...

They rearranged their shop.Â* And their old rs232 capable
laptop died on them.

The new laptop has no issues as there is a table in front
of the the CNC machine that they sit the laptop on.Â* It
just does not have an RS232 parts.Â* So they have to
eyeball transcribe their jobs.

The iMac was moved about 20 feet away as the crow flies,
so probably 80 feet cable distance.

Everyone is well within 2400 baud range.Â* Probably
9600 baud too.Â* The 64,000 dollar question is how
will the adapter I picked out respond to hardware control,
if that is what the CNC machine is using.Â*Â* I have asked
the customer for the model number of the CNC machine
to see if I can get a manual.

Thank you for the tips!

Well, if 'a couple' is two, then you probably would have needed RS232
at some point to connect things like modems, printers, etc., so no, you
weren't old then, nor now. [1]

Yep. I used external dial-up modems back then and laplink cables. I
don't think I ever use printers on those COM/serial ports since I used
parallel.


I have seen serial port printers, used with non PCs. With 5ESS Lucent
switches. I was amazed when I saw them on 1997, no idea where they got
them from. Wide carriage, ribbon. Brand name.

Turns out the parallel port is a PC thing. Implementing an RS232 is easier.
