v1.3.2

• Bug fixes
  • Fix incorrect switch in C that caused flow control enum to be incorrect.
    Thanks to Lee Bannard

v1.3.1

• Bug fixes

  • Lengthen timeouts on messages sent to ports. This provides more slack time
    on heavily loaded uniprocessor devices that were missing timeouts by ~100 ms
    periodically.
  • Move C object files and the port executable to under the _build directory.
    This makes it easier to switch between host/target builds especially when
    using Elixir 1.8's mix target feature.

• Improvements

  • Handle iodata on Circuits.UART.write in addition to binaries and
    charlists.

v1.3.0

Rebrand to Circuits.UART. No features or bugs were fixed in this version. To
upgrade, you will need to rename all occurences of nerves_uart to
circuits_uart and Nerves.UART to Circuits.UART.

v1.2.1

• Bug fixes
  • Added missing ignore parity option to parity checking choices
  • Fix compiler warnings when built using newer versions of gcc

v1.2.0

• Improvements
  • Added id: pid option. In active mode, this causes the receive
    notification messages to contain the pid of the Nerves.UART GenServer that
    sends them. Thanks to Tallak Tveide for this improvement.
  • Added find_pids/0 diagnostic utility for finding lost Nerves.UART pids.
    This is handy when you need to close a serial port and don't know the pid.
  • Added configuration/1 to get the current configuration of a UART.

v1.1.1

The mix.exs file has the Elixir requirement bumped from 1.3 to 1.4. This was
done to fix a Dialyzer warning caused by a change in arguments to
System.monotonic_time/1 with newer versions of Erlang and Elixir.
Unfortunately this broke compilation under Elixir 1.3.

• Bug fixes
  • Removed unnecessary open failure notification message. The failure gets
    returned from the open call already and the notification was due to an
    unfortunate path through the Linux filehandle polling code.
  • Various Windows fixes:
    • Fixed unhandled tx ready event seen during big transfers at 250000.
      Thanks to Arne Ehrlich for figuring this out.
    • Fixed bogus file handle errors when an open fails and then an attempt to
      open again happens without a restart of the GenServer.

v1.1.0

• Improvements

  • Added 4-byte framer both since it is periodically useful and as a very
    simple example of the framing feature.

• Bug fixes

  • Fix active mode state not being updated and a message being sent in
    passive mode on an open failure.
  • Maintain the elapsed time on passive mode reads to avoid reading forever
    when bytes keep arriving, but no messages get sent from the framer

v1.0.1

• Improvements
  • Refactored Makefile logic to avoid 1-2 second hit when building. This was
    due to erl being called to get the directory containing the erl interface
    include/lib paths. Now mix.exs passes them down.
  • Trivial Elixir 1.6 formatting tweaks

v1.0.0

• Bug fixes
  • Flush framing when closing a port
  • Fix broken spec's
  • Documentation and code cleanup

v0.1.2

Prebuilt port binaries are no longer distributed in hex.pm for Windows users.
You'll need to install MinGW. Feedback was that it didn't work as well as I
thought it would.

• Bug fixes
  • Fix custom baudrates not working on OSX. Thanks to salzig for identifying
    the problem and helping to debug it.
  • Pass flush request through to framer as well as the serial port. Thanks to dhanson358 for this fix.
  • Minor code cleanup
