Internal SDO requests now synchronized with external requests.
Internal SDO requests are managed by master FSM and can conflict with
external requests managed by slave FSM. The internal SDO requests
includes SDO requests created by an application and external request are
typical created by EtherCAT Tool for SDO upload/download or a directory
fetch initiated with ethercat sdos command. The conflict will cause a
FPWR from an external request to be overwritten by a FPWR from an
internal SDO request (or oppersite) in the same "train" of datagrams.

Virtual TTY interface driver for EtherCAT slave supporting serial comm

Quick installation guide:

./configure --with-linux-dir=/your/linux/directory --enable-tty
make all modules
make modules_install install
rcethercat start
insmod tty/ec_tty.ko
insmod examples/tty/ec_tty_example.ko

The default settings for the serial line are 9600 8 N 1.

The tty example operates a Beckhoff EL6002 at ring position 1. For a short
test, connect port X1 with a serial port via null modem cable. If a minicom is
started on that port and the below command is entered, the output should be
visible in minicom:

echo "Hello World" > /dev/ttyEC0

Have a lot of fun!
