If I see it right there could be a segmentation fault if used in echo mode. When you choose echo mode the variable message wouldn't a value assigned and in the cleanup function the not allocated memory would be free'ed.

Option -c enables flowcontrol with rts and cts, for none RS485 mode.
Option -t adds a delay after the reception of the first byte, usable to
test the flowcontrol.

Add qml implementation of bouncing ball to be used with qmlscene.
Add itu background images in png format.

For the TANARO platform we need to initialize the keypad and test it.
Add the corresponding scripts and Makefile hint.

The line endings were set to DOS (carriage-return + linefeed)
Set it to unix instead.

With this also change the subdir variable to multi line and order it.

Uses the Packageformat from RS485 test, works with direct loopback.
Don't uses additional threads, so no syncronisation problems.

Some test are compiled into bit, so the time consuming fork process can
be omitted. With -n this can be disabled now.

rand was initialized with time(0) which led to the same data if started
twice in the same wall time second.
Now also taking nanoseconds into acount.

The rs485pingpong test is replaced by rs485echo test, which turns out to
be more stable.

Add a pthread barrier to synchronize the Rx/Tx threads and remove the
Tx pipe as it becomes useless.

This fixes the issue when the serial test is run inside bit.

BCS 746-000147

Add the possibility to use a TCP connection for the echo client.
The code is well prepared for this and you simply need to activate
the correct parameter parsing and connect the socket to the server.

Additionally to activating the TCP connection we have to wait for the
whole package to arrive.

As a refactoring step sue a simple division instead of a conditional
shift to get a loop boundary.

The ```gettimeofday()``` function is defined in ```sys/time.h```. Thus
include it.

For concurrency and synchronization issues we need a new approach.
The select() function and additional pipes should be sufficient to
timeout and synchronize the TX source and Rx sink thread.

* Add RS485 echo test for our EMC verification.
* The test is more flexible than the legacy RS485 ping pong test and will
  always recover from transmission errors due to EMI.
* The sent data includes a hard-coded 4-byte header and a 4-byte data length
  field, which is parsed by the receiver. The receiver always scans the
  received data for the header bytes in order to detect a new message.

The usleep did not fix the broken Microchip MCP25XXFD CAN driver.
To resolve the issue we need to update the driver, thus remove the
sleep.

The pthread_cond_signal should be called with the mutex locked.
Thus move the unlock after the signal.

Add an usleep(1000) before closing the CAN socket. Some drivers have
some kind of race condition sending data and closing the socket.

iptest assumed sizeof(unsigned long) == 4, which fails on aarch64. fixed
this.

* Our hardware supports more baud rates than the test did. Add support for baud rates above 230400.

* @aio@ tool can now use device-names of the form
** e.g. @iio:device0/in_voltage_raw@ to specify devices relative to @/sys/bus/iio/devices/@, as before
** or e.g. @/dev/ain1/in_voltage_raw@ to specify absolute device names

Change-Id: Id0e38ea614e03b3f3363209a5ce3af21c5a7fb0a

* added new parameters @-f@ and @-g@ to override the IIO scale values reported by the system

Change-Id: I02e4bce2a4ab7a22bf9be54470890857e811ab70

* added option @-m@ to apply a median filter to the input
* added option @-a@ to apply an average filter to the input

Change-Id: Ic8a6e7de08f4280de418f12f7126da003b395e26
Note: The new option are mutually exclusive with each other and the @-r@ (dummy read) option

* added new "-d" parameter to specify a delay (in milliseconds) between setting the output and reading the input to allow for slower hardware (esp. galvanically isolated DIOs).

* renamed the "-v"-parameter to specify the value to be set/expected to "-e" instead to fix a parameter collision with "-v" for verbose output.
* replace usage of "-v"-paramter in runtest files with new "-e"-paramter

Change-Id: I9c31d2d3840ce9e1a1ba0baa1f5fecf76188fa5b

* renamed "-i"-parameter to set the IIO input-device to "-s" to fix collision with LTP "-i <iterations>"-parameter

* The built in test called internally instead of using system to call a shell where the command is executed.
* They need to be split up in setup/run/cleanup
