In 1981, the automated cellular NMT network (Nordic Mobile Telephone) replaced the old operator-assisted mobile phone network. It was an immense success in the Nordic countries, and prevailed long after the introduction of GSM, much because 450 MHz NMT had much greater coverage than 900 MHz GSM.
In the US, I guess this has minor or no importance, though...

Mid '91 I was the first in the company to get a Motorola MicroTAC II flip. All the goodies too. 3 different sized batteries, car kit....
The salesmen who had been lugging round "bricks" (DynaTAC) were sooo jealous that a techo got a nicer phone. 
Battery life was not a great thing in those NiCd days. There were a few hours-long international conference calls where I had to make a quick battery swap and rejoin the call.
It replaced a pager, which was nice. The nature of the business was such that most of the support calls from ops were between 1am and 4am. I could now respond to the trivial ones without getting out of bed. And if I had to get out of bed, I could talk to them while the landline was tied up with the dial-up modem.
Replaced by some candybar Nokia I don't remember when AMPS was phased out for CDMA.
And I am older than the (bipolar) transistor.

I guess their definition of a mobile phone is "Handheld".
Ericsson designed their first fully automated mobile phone system for vehicles in 1956, it weighed a whopping 40 kg though.

The ones before that were 'manual'???

There were mobile phone systems before that where you had to order a call from the exchange.
The border between a mobile phone system and a glorified radio is a bit fuzzy, but the Ericsson MTA had a rotary dial and automatic connection to the normal telephone system.

Well that is interesting.

All I had was a pager and the nearest phone box. I could not afford a mobile phone.
Mobile phones are for making and receiving calls and texts. Beyond that, the screen size is way too small for me.

Not for cellphone, no...
But in 1986 I was issued with a company (EDS) pager for overnight support. It seemed miraculous at the time - receiving instant messages whereever I was, with a little (16 character?) display. There were three of us on the project supporting a credit card processing application, with one each night on support and one on "backup" support. So that was four nights a week we were "on duty" with a pager. EDS being what it was, there was a strict "no drinking" rule whilst on duty; however the team often met socially after work. One night my colleague's pager went off, and it got "accidentally" dropped in his pint. When I got home about an hour later, mine (as backup) also went off. Fortunately the fix for the production issue was trivial and ops were able to resolve it without me dialling in (we also had a portable teletype unit and modem with acoustic coupler!), which by then was just as well...

Both actually, if you're interested in MS products.
The noise about Bluetooth had me thinking too ... but in terms of Windows.
My Google of "MSDN c# bluetooth file transfer" yielded virtually nothing worthwhile in the first x pages (note the use of MSDN which tends to (usually) surface better results).
The same query in Bing then yielded at #2: "Bluetooth RFCOMM"
Quote: This article provides an overview of Bluetooth RFCOMM in Universal Windows Platform (UWP) apps, along with example code on how to send or receive a file.
... "exactly" what I was looking for but was afraid to ask.
Subsequently querying Google on "uwp bluetooth rfcomm" yielded a swath of useful results.

... if you use it in a Web Backend implementation?
Does the front end then needs to have to display all these packages anywhere?
Or is it enough to have a license text file on the server?

First of course read it and understand it.
And there is no such thing as "MIT License" legally. You need to get the text of the exact license. I suggest also that you do the following for each library
1. Document where you got the library - the url
2. Document the date when you got it.
3. Document, in text, where you pulled the license from.
4. Copy that license. Definitely do not rely on the original url (#1) to find the license in the future.
5. Do NOT automate pulling new versions. They can change the license anytime they want.
If you are concerned about your understanding (not whoever posts here) then you should hire a lawyer with experience in Software.

I looked at the following and then read what it says about X11 (a version). That is limited to the following
1. That version
2. That what is posted there is correct.
3. My understanding.
MIT License - Wikipedia[^]
Based on that it says nothing at all about maintaining the copyright (other licenses do that) in any form.
Rather it tells you that you cannot use the copyright notice at all. So the exact opposite of what you are suggesting. It should not be in the web pages and it should not be in the backend either.
This terminology is to insure that you (or someone else) cannot attempt to copyright the original library code yourself and thus keep others from using it.

First of all, thank you very much for your answer.
A lot of material which I have to process first.
For the wiki: No, sorry, I would never trust a wiki publication regarding to legal stuff.
Thanks again.

It has nothing to do with the rest of your application. Not the code and not what your code displays.

Your understanding is wrong.
"You cannot use the copyright notice", as you frame it, basically means you can't copy-paste the copyright notice of someone else, with someone else's name on it, for your own work. You need your own license for your own work, and that license can also be MIT-X11 if you choose so.
That being said, you need to keep the original work and the original license together.
If you use a library under MIT-X11 on the backend, you need to provide the license on the backend as well.
|

MIT-X11 is a permissive license.
Simplified, you keep the original code as-is, and you make sure to keep the license text and the code together.
If you've used the code in a project with a package manager, the license text is included automatically.
If you've downloaded the code from GitHub, just don't delete the license.
If the code is deployed on the backend, you need the license somewhere on the backend as well.
Additionally:
If you modify the original work, you cannot slap a new license on the entire thing and say it's your work now.
If you build something with it or change something, you can license your stuff however you want.
If something explodes, you can't sue the license holder of the original work for damages.
Pretty much all permissive licenses are like this, with the exception that some licenses require you to also communicate bugfixes and new features inside the original work to the original author. MIT-X11 does not requires this, but L-GPTL does, for example.

Does anyone know if there is a free desktop chat client that will talk to Teams?
There is no way I'm paying them $50/year to use their junk.

Well, there is Microsoft Teams (free)[^] which is what I switched to when they announced that Teams Classic (free) was closing.
Seems to work fine, but it doesn't import your contacts or settings, probably to persuade you to pay.

Oh Microsoft, you so silly. That will be fine. They kept popping up the non-free one with no mention of the renamed version. Microsoft Marketing - driving people mad since 1985.

So why use it at all?
If your clients use it then, regardless of your feelings, then you must use it. And the cost is a business expense. Or even something you can bill them for (each client actually.)
If it is a company thing then the company should be paying for it.
If friends/family then of course you could just stop talking to them.

Well true, but sometimes I'm talking to past coworkers whose company has drunk the Kool-Aid.
