UART in RTEMS

No, i have a very low baudrate, 2400. The device is /dev/console_b, as
instructed in

http://www.gaisler.com/cms/index.php?option=com_content&task=view&id=82&Itemid=61

After doing some tests i'm now sure that the packets are lost on the
processor side. The processor is not fast enough to process the application
and read the incoming packets in time, hence resulting in synchronization
problems. The receiving sequence is lost because some packets are not
"grabbed". I wonder if this can be improved by increasing the UART HW
fifo..?


Best,
JM
