+atarisio (peripheral emulator for Atari 8-bit computer and SIO2PC)
+
+AtariSIO allows a Linux system to act as one or more disk drives,
+a printer, and/or a cassette drive for an Atari 8-bit (400/800/XL/XE)
+computer, using an SIO2PC cable.
+
+Even without SIO2PC or a real Atari, this package includes some
+utilities that are useful for manipulating and examining Atari disk,
+cassette, and executable images.
+
+AtariSIO can use either a regular serial port or its own kernel
+driver. The kernel driver requires a real serial port with a 16550A
+UART, which is fairly rare on modern PC hardware. The regular serial
+port mode works with most USB serial port adaptors. For best results,
+use an FTDI-based adaptor.
+
+By default, the kernel driver is not built because it's not very
+useful (or even functional) on modern PCs. To enable it, read the
+instructions in "README_kernel.txt".
+
+By default, the atariserver and atarixfer executables are installed
+setgid dialout so they can access the serial port, and have the
+appropriate capability bits set so they can use realtime scheduling.
+
+If you don't like this, you can set SETGID=no in the script's
+environment, and run the programs as root (e.g. with su or sudo).
+
+If you're using a filesystem that doesn't support capabilities,
+you can instead set SETUID=yes in the script's environment, to make
+atariserver and atarixfer run as root.

+*******************************************************************
+* If your serial port is a USB adaptor, STOP reading this NOW and *
+* go build atarisio _without_ KERNEL="yes"!                       *
+*******************************************************************
+
+AtariSIO's atariserver and atarixfer use your serial (RS232) port to
+communicate with the SIO2PC device. This can be done one of two ways:
+using the regular Linux serial port driver or a special AtariSIO
+kernel driver that "takes over" the serial port [1].
+
+The kernel driver exists because the SIO protocol relies on tight
+timing, especially when using high bitrates (lower POKEY divisor
+numbers). On older machines, scheduling latency can cause "hiccups"
+in the SIO transfers, resulting in slow loading (due to retries)
+or failures.
+
+On modern machines (especially with modern kernels), there's less of
+a need for the kernel driver. Also, modern computers don't often have
+real serial ports. It's still possible to use AtariSIO with a USB to
+RS232 adaptor on such a machine, but not with the kernel module.
+
+The AtariSIO kernel driver can only be used if you have a real (not
+USB) serial port that uses a 16550A or 100% compatible UART. If you're
+using USB, stop reading this and build atarisio without KERNEL=yes.
+
+Also, even if you do have a real 16550A serial port, you still might
+want to avoid the kernel driver: if atarisio works fine without it,
+there's no need for the kernel driver's extra complexity.
+
+If you're determined to use the kernel driver, read on.
+
+1. Build atarisio with KERNEL=yes [2].
+
+2. Install the atarisio package you just built.
+
+3. The atarisio module needs to know which serial port to use. The
+   default is /dev/ttyS0. If you only have one serial port, this
+   should be the correct one. If you need to change this, edit
+   /etc/modprobe.d/atarisio.conf and change the "port=/dev/ttyS0" to
+   whatever it should be.
+
+4. As root, run "modprobe atarisio". The module will be loaded on
+   every boot; this step is just to avoid rebooting. If you don't
+   want to load the module at boot, edit /etc/rc.d/rc.modules.local
+   and comment out the "/sbin/modprobe atarisio" line.
+
+At this point, you should be ready to run atarisio. If you have
+trouble with the kernel module, try building atarisio without it and
+see if it works. If not, there's probably something wrong with your
+hardware.
+
+Notes:
+
+[1] The SlackBuild author hasn't tested the kernel module. I don't
+    currently own any machines with 16550A serial ports, only USB.
+    I used to use the kernel module with older hardware (up to 2016
+    or so) and it worked fine then.
+
+[2] If building the kernel module fails, it means your kernel is too
+    new for atarisio. The current version of atarisio works with
+    kernels up to 5.15.x (which is what Slackware 15.0 runs). If
+    you're running Slackware-current and can't compile the kernel
+    module, tough luck (for now anyway). Use atarisio without the
+    kernel module, or use Slackware 15.0.

+  - The metadata for each block:
+
+    - Block Number
+    - Record Type (data or fsk)
+    - Part (0 for the first file/stage, 1 for the 2nd, etc)
+    - Baud (bits/sec; normally 600)
+    - Gap aka PRWT (Pre-Record Write Tone, in milliseconds)
+    - Block length in bytes (normally 132)
+
+If an invalid file (not a CAS image) is given, **casinfo** will print
+**Error: "file" doesn't start with FUJI header** to stderr, then
+exit. Beware that the exit status is always 0 (success), so a script
+would have to capture and parse stderr to catch errors.
+
+EXAMPLE
+=======
+
+::
+
+   $ casinfo test.cas
+   casinfo 0.30-210714 (c) 2007-2010 Matthias Reichl
+   infos for "test.cas":
+   Description: <none>
+   Number of Parts: 1
+   Number of Blocks: 3
+      0:  data part:  0  baud:   600  gap: 25647  length:   132
+      1:  data part:  0  baud:   600  gap:   252  length:   132
+      2:  data part:  0  baud:   600  gap:   254  length:   132

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
