Hello sir,

oh, it seems to work perfectly, i don't know why it works in this case when i lauched it in the terminal linux, i copied exactly the program in Eclipse C++ and it doesn't work. Ah the only thing i have changed (otherwise my program don't compile in Eclipse), is 

static const struct rtser_config read_config = {
0xFFFF,
115200,
RTSER_DEF_PARITY,
RTSER_DEF_BITS,
RTSER_DEF_STOPB,
RTSER_DEF_HAND,
RTSER_DEF_FIFO_DEPTH,
RTSER_DEF_TIMEOUT,
RTSER_DEF_TIMEOUT,
1000000000, /* 1 s */
RTSER_RX_TIMESTAMP_HISTORY,
RTSER_EVENT_RXPEND,
};

static const struct rtser_config write_config = {
RTSER_SET_BAUD | RTSER_SET_TIMESTAMP_HISTORY,
115200,
RTSER_DEF_TIMESTAMP_HISTORY,
/* the rest implicitely remains default */
};

maybe, i don't compile with good parameters in Eclipse?
my version Xenomai 2.6.0

What version (cat /proc/xenomai/version)?

That bogous! Please try the image created as shown below:

 $ cd <xenomai-2.6-path>/examples/rtdm/profiles/serial
 $ make XENO=/usr/xenomai/bin
