-------------------
-
-Note: This release does NOT change the libserialport API or ABI in
-      backwards-incompatible ways. Programs using libserialport should
-      continue to work fine without recompiling or relinking.
-
- * New API calls:
-   - sp_get_port_description(): Obtain a user friendly port description.
-   - sp_get_port_transport(): Obtain the underlying transport type.
-   - sp_get_port_usb_bus_address(): Obtain the USB bus number & device address.
-   - sp_get_port_usb_vid_pid(): Obtain the USB VID and PID.
-   - sp_get_port_usb_manufacturer(): Obtain the USB manufacturer string.

-     returning as soon as any data is available.
- * API related additions:
-   - enum sp_mode: Add SP_MODE_READ_WRITE.
-   - Add enum sp_transport with the following enum entries:
-     SP_TRANSPORT_NATIVE, SP_TRANSPORT_USB, SP_TRANSPORT_BLUETOOTH.
- * Fix the build on platforms where port enumeration and/or port
-   metadata is not available or implemented.
- * Build system:
-   - Don't set/override "user variables" such as CFLAGS or LDFLAGS, since
-     those are meant to be controlled by the "user" (bug #577).
-   - Modernize and cleanup autotools setup.
- * Remove trailing commas in libserialport.h enum definitions to allow
-   the code to build with the -pedantic compiler option.
- * Fix various issues to allow successful builds with -std=c99.
- * Fix various (non-fatal) compiler warnings.
- * Fix various memory leaks (bug #419, among others).
- * Fix a potential overflow of the timeout parameter of poll().
- * Fix ReadFile() ERROR_IO_PENDING in sp_nonblocking_read() (bug #707).
- * Fix a glibc >= 2.20 compiler warning for deprecated _BSD_SOURCE (bug #716).
- * Rename a 'signals' parameter to 'signal_mask' to avoid a conflict with Qt.
- * Fix two potential segfaults in sp_get_port_handle() and sp_get_config_*()
-   (which only occurred if the user incorrectly passed in a NULL argument).
- * sp_list_ports(): Actually set list_ptr NULL as documented.
- * Use "Port not open" debug message when a closed port is used (bug #710).
- * Linux:
-   - The libudev requirement has been dropped (/sys is now used directly).
-   - Fix a build issue in the get_termios_get_ioctl() call (bug #396).
-   - Fix sp_flush() so that it only flushes the requested buffers.
-   - Fix a build error if BOTHER is not available (bug #363).
-   - If present, add the USB "description" for better port identification.
-   - Handle the case when /sys/class/tty/ entries are not symlinks.
- * Windows:
-   - MinGW-w64 (mingw-w64.sf.net) is now required for building, and MinGW
-     (mingw.org) is no longer supported (bug #393).
-   - Fix a build issue due to a missing <initguid.h> #include.
-   - Fix a build issue due to the missing -lsetupapi linker argument.
-   - Use libtool's -no-undefined option to allow shared (DLL) builds.
-   - Fix a compile error due to multiply or not defined GUIDs (bug #416).
-   - Fix a build issue related to the SP_PRIV/SP_API macros (bug #553).
-   - Fix a bug where an uninitialized pointer was free()'d (bug #512).
-   - Fix a bug wrt the SetupDiOpenDevRegKey() return code (bug #499).
-   - Fix a bug wrt restart of RX/error wait operations after read (bug #421).
-   - Fix a bug wrt WaitCommEvents() and/or fAbortOnError handling (bug #341).
-   - Fix USB iSerial queries on USB composite devices.
-   - Strip CR/LF from end of system error messages (bug #585).
-   - Avoid unnecessary calls to the SetCommTimeouts() function (bug #586).
-   - Fix a bug in the Windows implementation of sp_blocking_read_next().
-   - Fix an ERROR_SEM_TIMEOUT related issue in sp_blocking_write().
- * FreeBSD:
-   - Implement serial port enumeration for FreeBSD systems.
- * Android:
-   - Fix a portability issue wrt the unavailable 'serial_struct' (bug #376).
-   - Fix a portability issue wrt a readlinkat() call (bug #377).
- * Mac OS X:
-   - Fix port listing on Mac OS X 10.11 (El Capitan).
- * README: Various documentation updates and fixes.

 - Reading, writing and flushing data.

 The library should build and work on any Windows or Unix-based system. If it
 does not, please submit a bug.
 
-Enumeration is currently implemented on Windows, Mac OS X, FreeBSD and Linux.
-On other systems enumeration is not supported, but ports can still be opened
-by name and then used.
+Enumeration is currently only implemented on Windows, Mac OS X and Linux. On
+other systems enumeration is not supported, but ports can still be opened by
+name and then used.
 
 If you know how to enumerate available ports on another OS, please submit a bug
 with this information, or better still a patch implementing it.
 
+Future
+======
+
+Future versions will add additional API calls for obtaining metadata about a
+port, e.g. for USB devices the USB VID and PID of the underlying device.
+
 Dependencies
 ============
 
-No other libraries are required.
+On Linux, libudev is required. On other systems no other libraries are required.
+
+The libudev dependency could be eliminated in favour of direct sysfs queries at
+the cost of some brevity. This is not currently a priority but if you feel like
+doing this feel free to submit a patch.
 
 Building
 ========
 
-On Windows, libserialport can be built with Visual Studio 2019 or with
-the standalone MSBuild tool, using the solution and project files provided.
-
-For other environments, the package uses a GNU style build based on autotools.
+The package uses a GNU style build system and requires a Unix style shell.
+On Windows it can be built with the MinGW toolchain and MSYS environment.
 
 Run "./autogen.sh" to generate the build system, "./configure" to setup, then
 "make" to build the library and "make install" to install it.
 
-Windows builds can also be created using the autotools build system, using the
-MinGW-w64 toolchain from http://mingw-w64.sourceforge.net/ - either natively
-in Windows with the MSYS2 environment, or cross-compiling from another system.
-
-To build from MSYS2, the following packages must be installed: autoconf,
-automake-wrapper, libtool, make, and either mingw-w64-i686-gcc (for 32-bit)
-or mingw-w64-x86_64-gcc (for 64-bit). Open either the "MSYS2 MinGW 32-bit" or
-"MSYS2 MinGW 64-bit" command window from the Start menu and use this when
-configuring and building the package. Using the "MSYS2 MSYS" shell will build
-against the Cygwin compatibility layer; this works, but port enumeration and
-metadata will not be available, and binaries will depend on Cygwin. The builds
-produced by MinGW-w64 are normal Windows DLLs without additional dependencies.

-This directory contains example programs showing how to use libserialport.
-
-The examples currently included are:
-
-list_ports.c - displays a list of ports on the system.
-port_info.c - displays info about a particular port on the system.
-port_config.c - sets and displays configuration settings on a port.
-send_receive.c - loopback test sending & receiving data on 1 or 2 ports.
-await_events.c - awaits receive events on multiple ports simultaneously.
-handle_errors.c - demonstrates handling errors returned from the library.
-
-The programs themselves are completely OS-independent, and require only a
-C compiler and libserialport.
-
-The 'examples.sln' file is a solution file for Microsoft Visual Studio 2019
-which will build libserialport and all of the example programs.
-
-The Makefile in this directory will attempt to build all the examples,
-using 'gcc' to compile them and 'pkg-config' to discover the include
-paths and linker settings needed to build with libserialport. It provides
-a minimal example of how to write a Makefile to build a program using
-libserialport.
-
-If you have make, gcc, pkg-config and libserialport installed correctly
-then running 'make' should build the example programs in this directory.
-If this doesn't work, you may need to modify the Makefile or set necessary
-paths in your environment to suit your system.
-
-You can also build these examples using any other compiler, IDE or build
-system. You just need the libserialport.h header available to compile them,
-and the libserialport library available to link and run them.
-
-These example files are hereby released into the public domain by the author.

-/*
- * FreeBSD platform specific serial port information:
- *
- * FreeBSD has two device nodes for each serial port:
- *
- *  1) a call-in port
- *  2) a call-out port
- *
- * Quoting FreeBSD Handbook section 26.2.1
- * (https://www.freebsd.org/doc/handbook/serial.html)
- *
- * In FreeBSD, each serial port is accessed through an entry in /dev.
- * There are two different kinds of entries:
- *
- * 1) Call-in ports are named /dev/ttyuN where N is the port number,
- *    starting from zero. If a terminal is connected to the first serial port
- *    (COM1), use /dev/ttyu0 to refer to the terminal. If the terminal is on
- *    the second serial port (COM2), use /dev/ttyu1, and so forth.
- *    Generally, the call-in port is used for terminals. Call-in ports require
- *    that the serial line assert the "Data Carrier Detect" signal to work
- *    correctly.
- *
- * 2) Call-out ports are named /dev/cuauN on FreeBSD versions 10.x and higher
- *    and /dev/cuadN on FreeBSD versions 9.x and lower. Call-out ports are
- *    usually not used for terminals, but are used for modems. The call-out
- *    port can be used if the serial cable or the terminal does not support
- *    the "Data Carrier Detect" signal.
- *
- * FreeBSD also provides initialization devices (/dev/ttyuN.init and
- * /dev/cuauN.init or /dev/cuadN.init) and locking devices (/dev/ttyuN.lock
- * and /dev/cuauN.lock or /dev/cuadN.lock). The initialization devices are
- * used to initialize communications port parameters each time a port is
- * opened, such as crtscts for modems which use RTS/CTS signaling for flow
- * control. The locking devices are used to lock flags on ports to prevent
- * users or programs changing certain parameters.
- *
- * In line with the above device naming USB-serial devices have
- * the following naming:
- *
- * 1) call-in ports: /dev/ttyUN where N is the port number
- * 2) call-out ports: /dev/cuaUN where N is the port number
- *
- * See also: ucom(4), https://www.freebsd.org/cgi/man.cgi?query=ucom
- *
- * Getting USB serial port device description:
- *
- * In order to query USB serial ports for device description - the mapping
- * between the kernel device driver instances must be correlated with the
- * above mentioned device nodes.
- *
- * 1) For each USB-serial port (/dev/cuaUN) use libusb to lookup the device
- *    description and the name of the kernel device driver instance.
- * 2) Query sysctl for the kernel device driver instance info.
- * 3) Derive the ttyname and (serial) port count for the kernel device
- *    driver instance.
- * 4) If sysctl ttyname and port matches /dev/cuaUN apply the libusb
- *    device description.
