Dear Maintainer,
here are some notes and editorial fixes for the manual.
The patch is in the attachment.
-.-
The difference between the formatted outputs can be seen with:
nroff -man <file1> > <out1>
nroff -man <file2> > <out2>
diff -u <out1> <out2>
and for groff, using
"printf '%s\n%s\n' '.kern 0' '.ss 12 0' | groff -man -Z - "
instead of "nroff -man"
Add the option "-t", if the file contains a table.
Read the output of "diff -u" with "less -R" or similar.
-.-.
If "man" (man-db) is used to check the manual for warnings,
the following must be set:
The option "-warnings=w"
The environmental variable:
export MAN_KEEP_STDERR=yes (or any non-empty value)
or
(produce only warnings):
export MANROFFOPT="-ww -z"
export MAN_KEEP_STDERR=yes (or any non-empty value)

Mark a full stop (.) and the exclamation mark (!) with "\&",
if it does not mean an end of a sentence.
This is a preventive action,
the paragraph could be reshaped, e.g., after changes.
When typing, one does not always notice when the line wraps after the
period.
There are too many examples of input lines in manual pages,
that end with an abbreviation point.
This marking is robust, and independent of the position on the line.
It corresponds to "\ " in TeX, and to "@:" in Texinfo.
184:This requires being root, unless the non-root user happens be logged into the virtual console and be using that specific virtual console device like e.g. \fB/dev/tty4\fR. This makes the console driver useless for non-root users logged in via ssh, and often X11 or Wayland.
193:with 2050Hz comes in, you will hear that 2050Hz beep for 100ms, and then silence as the quick beep silences the tone generator. Now you will not hear that the first \fBbeep\fR process is still running after having waited for the first 2100ms of its 10000ms. You will also not hear that the first \fBbeep\fR process will silence the already silent speaker 7900ms later, i.e. 10000ms after the first \fBbeep\fR started.

Use the correct macro for the font change of a single argument or
split the argument into two.

N.B. - (0x2D), processed as a UTF-8 file, is changed to a hyphen

Wrong distance between sentences.
Separate the sentences and subordinate clauses; each begins on a new
line. See man-pages(7) ("Conventions for source file layout") and
"info groff" ("Input Conventions").
The best procedure is to always start a new sentence on a new line,
at least, if you are typing on a computer.
Remember coding: Only one command ("sentence") on each (logical) line.
E-mail: Easier to quote exactly the relevant lines.
Generally: Easier to edit the sentence.
Patches: Less unaffected text.
Search for two adjacent words is easier, when they belong to the same line,
and the same phrase.
The amount of space between sentences in the output can then be
controlled with the ".ss" request.
N.B
The number of lines affected is too large to be in the patch.
67:Beep for a tone length of \fILEN\fR milliseconds. Default value: 200 ms.
70:Repeat the tone including delays \fIREPEATS\fR times. Default value: 1 tone, not repeated.
73:Specify a delay of \fIDELAY\fR milliseconds between repetitions. Small letter \fB\-d\fR specifies that this delay should only occur \fIbetween\fR beeps, that is, it should \fInot\fR occur after the last repetition. Capital letter \fB\-D\fR specifies that the delay should occur after every repetition, \fIincluding\fR after the last one. Normally, \fB\-d\fR is what you want, but if, for example, you are stringing several \fBbeep\fR commands together to play the star wars anthem, you may want control over every delay. Default value: 100 ms delay between beeps with no delay after the last beep.

Appropriate break points are the end of a sentence and a subordinate

\fBbeep\fR allows the user to control the PC speaker with precision, allowing different sounds to indicate different events. While \fBbeep\fR can be run quite happily on the command line, \fBbeep\fR's intended use is within shell/perl scripts, notifying the user when something interesting occurs. Of course, it has no notion of what \fIIS\fR interesting, but it is good at the notifying part.
beep.1: line 47 length 245
All options have default values, meaning that just typing '\fBbeep\fR' will work. If an option is specified more than once on the command line, subsequent options override their predecessors. So '\fBbeep\fR \-f 200 \-f 300' will beep at 300Hz.
beep.1: line 49 length 125
All durations are given in a unit of milliseconds, frequencies as Hertz, and the number of repeats is a dimensionless number.

Explicitly set the device \fBbeep\fR shall use to generate beep tones. When not given a device explicitly, \fBbeep\fR runs through an internal list of devices until one appears to work.
beep.1: line 64 length 328
Beep with a tone frequency of \fIFREQ\fR Hz, where 0 < \fIFREQ\fR < 20000. As a general ballpark, the regular terminal beep is around 750Hz. For backwards compatibility, you can give \fIFREQ\fR as a floating point number, but \fBbeep\fR will round that to integer values as the kernel APIs expect them. Default value: 440 Hz.
beep.1: line 70 length 90
Repeat the tone including delays \fIREPEATS\fR times. Default value: 1 tone, not repeated.
beep.1: line 73 length 600
Specify a delay of \fIDELAY\fR milliseconds between repetitions. Small letter \fB\-d\fR specifies that this delay should only occur \fIbetween\fR beeps, that is, it should \fInot\fR occur after the last repetition. Capital letter \fB\-D\fR specifies that the delay should occur after every repetition, \fIincluding\fR after the last one. Normally, \fB\-d\fR is what you want, but if, for example, you are stringing several \fBbeep\fR commands together to play the star wars anthem, you may want control over every delay. Default value: 100 ms delay between beeps with no delay after the last beep.
beep.1: line 76 length 234
The \fB\-\-new\fR option allows you to chain multiple beeps together on a single command line. Each time the \fB\-\-new\FR is used, \fBbeep\fR starts treating all further arguments as though they were for a new beep. So for example:
beep.1: line 80 length 655
would produce a sequence of three beeps, the first with a frequency of 1000Hz (and otherwise default values), then a second beep with a frequency of 2000Hz (again, with things like delay and reps being set to their defaults), then a third beep, at 1500Hz. This is different from specifying a \fB\-r\fR value, since \fB\-r\fR repeats the same beep multiple times, whereas \fB\-\-new\fR allows you to specify different beeps. After a \fB\-\-new\fR, the new beep is created with all the default values, and any of these can be specified without altering values for preceding (or later) beeps. See the \fBEXAMPLES\fR section if this managed to confuse you.
beep.1: line 83 length 322
Both the \fB\-s\fR and the \fB\-c\fR option put \fBbeep\fR into input processing mode, reading from \fIstdin\fR and copying all received data to \fIstdout\fR. This makes it easy to slip \fBbeep\fR into a text processing pipeline to acoustically monitor the data flow within that pipeline. See the \fBEXAMPLES\fR section.
beep.1: line 90 length 106
Beep after every set of data received. Usually, this means after newlines occur in text processing pipes.
beep.1: line 92 length 432
In a sequence of notes specified with one or more occurrences of \fB\-n\fR or \fB\-\-new\fR, it only makes sense to have one single note marked with either \fB\-s\fR or \fB\-c\fR attached to it. Then \fBbeep\fR will beep all notes until it reaches that marked note, then repeat the marked note according to the input it receives, and once the input has reached EOF, \fBbeep\fR will continue with the remainder of the note sequence.
beep.1: line 94 length 100
The behaviour of \fBbeep\fR with more than one note marked with \fB\-s\fR or \fB\-c\fR is undefined.

When you run \fBbeep\fR without explicitly giving a device to use, \fBbeep\fR tries opening the following devices in sequence until one succeeds:

Uses the evdev API, and system administrator can allow access to any set of users and groups using the normal file permissions.

Concurrent invocations of \fBbeep\fR are not supported. There is only one tone generator in the PC hardware, and we do not manage access to that shared resource in any way. So if a first

Now you will not hear that the first \fBbeep\fR process is still running after having waited for the first 2100ms of its 10000ms. You will also not hear that the first \fBbeep\fR process will silence the already silent speaker 7900ms later, i.e. 10000ms after the first \fBbeep\fR started.

however, chances are you have a piezo beeper connected to the mainboard. If you prioritize a loud beep over a certain frequency beep, you can choose to beep at a frequency close to the resonance frequency of the piezo beeper. Typical piezo beepers have a resonance frequency around 2000Hz, so you can test frequencies around that range. The author's piezo beeper is the loudest at about 2050Hz.

chances are that your laptop will not have a piezo beeper hardware inside and that it will route the output of the pcspkr circuit to the laptop's internal speakers via the sound card mixer. In that case, you can and/or must change the mixer level for the beeper using a sound card mixer application.
