That was not your original complaint, which was about how
complecting the serial port abstraction with the TTY layer
ultimtely proved to be a poor design choice.  You are correct
about that, for the record, but this complaint is a different
matter entirely.

What you're saying is that you really just want to get the TTY
layer out of the path between the user program and the serial
device.  That's fine, but different.

Concept of layers is too abstract for my poor mind.
Especially when there are more than 2 or 3 of them.

Systems is kind of weird in computer science (and other
disciplines) in the sense that conferences are the primary venue
where new material is presented.  Seems like you're cutting
yourself off from most of frontier of work in the subfield
arbitrarily, but you do you.

Hmmm, no.

About 25 years ago I wanted to synchronize my computer's clock to
the NIST Automated Computer Time Service [1] over a dialup modem.
The computer was an alphalinux with a 21164 if I remember correctly.
One core, but fast for the time.

NIST sends a ~50 character timestamp string, followed after a short pause
by a "*" on-time-marker. Reading the string one char at a time in a
tight loop didn't work, it dropped characters. Just saying.

The right way, in pseudocode:

    Set the fd for non-blocking reads;
    loop: {
	Select to read with a short timeout (2 ms or so at 9600 baud).
	Read what's available, appending to a buffer.
    }
    // timed out; that means we finished reading the string.
    {
	Select to read with a long timeout.
	Read the marker.
	(Read the system clock so we can calculate the delta later.)
	Echo the marker.
    }
    // That's one timestamp. Repeat for more, until NIST hangs up.

The select() call had plenty timeout resolution.  (You could use poll() too.)

(When you echo the marker, NIST measures the round-trip time, corrects
for it and changes the marker to a "#".)

Don't know if NIST still operates the service. I hope so, there are
many places left with no Internet access.

Reminds me a simple service that the PTB (in DE) offered 30 years ago
and that I was happily using to simply interrogate the UTC time from
the command-line in a _minimalist_ textual form by just interrogating
a PTB server at a specific port (and without specific protocol or tool)

gawk '
   BEGIN {"/inet/tcp/0/www.ptb.de/5076" |& getline time ; print time }
'

Only a few years later they discontinued that nice simplistic service.

Meanwhile they have a fancy GUI (https://uhr.ptb.de/ - nothing that I
could interrogate and process as simply as with above script).

A current alternative (but not exactly as simple as before) is going
through NTP with the respective tool as in:  ntpdate -q ptbtime1.ptb.de

Why letters and not descriptive volume names?  If I insert a USB
flash device into my Macintosh, it gets mounted under
`/Volumes/<some name>` where the name is a property of the image
on the drive; usually it's descriptive.  It also shows up in the
Finder as a separate thing that I can double-click on to expand
the view of in a window.

That seems infinitely better to me than what Windows does.

This conflates so many things that I don't even know where to
rightfully begin.  In particular, you are referring to the
actual directory pathnames that Linux uses as mount points for
the filesystems on devices.  But I see no reason why I couldn't
have a userspace image that creates symbolic links to those
named 'a', 'b', 'c', etc.

In general, that's a bad idea and poor practice anyway.  But if
you wanted to, you could assume a pathname that's a symbolic lnk.

Sounds like you can't assume that on Windows, either.

You could do something like

    dir=${dir:-/media/$LOGNAME/expected_volume_name/...}

...and then refer to things using names relative to $dir.
People have been doing things like that for half a century now.
It's relaly not that hard.

These are letters that are physical labels next to each socket. If I 
give instructions to somebody to use physical socket 'A', they can do 
that even if the machine is powered off.

If I look at the back of my TV, I have HDMI sockets marked 1, 2, 3. The 
same numbering appears on the on-screen A/V menu. It's simple and it works.

Content- or device-related labels can be shown too interrogated from 
whatever is plugged-in and active (that is, on-screen), but that is 
secondary.

Of course, when there are no dedicated cables and it is all wireless, 
then it gets harder and not so simple.

If I have two USB floppy drives plugged into a windows box,
which one is A and which one is B?  There are no labels on the
drives.

Not on my system.

Huh.  Kinda hard to access the files on the "A:" drive when the
system is powered off.  I would find it frustrating to type
commands to a machine that isn't even running.

So the Unix scheme assigns each floppy drive a number.  The only
substantive difference is that with Unix, you `mount` the
filesystem on the removable drive onto some directory, making
the files on that floppy appear as part of the global file
namespace.

None of this has to do with `fopen`.

This was hypothetical. That is, if USB sockets were labeled like my HDMI 
example and those letters or numbers appeared also on menus.

This is about plugging in the device, like I can plug in my PCV to HDMI1 
when the TV is still turned off.

Yet it hasn't stopped you having your say about a topic before declaring 
it as off-topic.

Those would probably be numbered, not identified by letters.  I
have never seen someone label USB ports like that.

I thought it was about naming conventions and shell scripts.
Before that, it was about `fopen`.

Hey, it's not my fault if Unix is too hard for you to understand
or use.  *shrug*

By default it’s using the device serial number to create a unique

It is possible to set up things to be case-insensitive, if you want.

I'd ask in a forum that discusses Unix-like systems, not one that
discusses the C programming language.

fopen() takes a pointer to a string as its first argument.
The requirements for that string are system-specific.

Here's the thing: this is thread that has been wildly off-topic for 
nearly 100 posts, even aside from the other off-topic threads.

Yet you pick on MY post and tell only ME to move the discussion elsewhere.

Why?

perhaps it is because _you_ are most often the poster who
moves the thread off-topic?

At the risk of speculating on Keith's motives, I think it is far 
simpler.  Bart asked how he would do something that was not C related, 
and Keith suggested he asked in a newsgroup where the question was 
topical.  That strikes me as perfectly reasonable, but it triggered 
Bart's paranoia.
