How do I use rtems_termios_bufsize?! No doc!

[João Rasta]

In order to discard hardware issues I now tried the same application on a
more powerful FPGA. Here the leon-3 processor runs at 80MHz and UART
hardware fifos size are doubled to 32 bytes. However the problem is still
the same. Rx works well, the packets received are ok but the packets sent
are not correct.

I suspect of a problem on the driver. If i set a big buffer, 1024 as chris
suggested, "trash" bytes are sent. This does not happen if i set a buffer
lower than the message i want to send but in this case i loose bytes.

Termios is well configured, the simplest way possible. I'm using POSIX rtems
support.

Can that warning on the driver be the problem? Transmissions in interrupt
mode not working well? Is there any other driver i can use?


Best,
JM
