Hi,

I'm waiting to post the code, cos it is not so clean to read, with the cut and paste it is not so easy to understand, I'll do soon a clear of the useless part, and then post it.

I enabled the fifo, so I can read up to 16 before the uart goes in failure, and up to store 16byte to be send.

At the moment, I managed to send more then 16 byte, when I get the interrupt request, I send max 16 bytes, if there are more bytes, I send the eoi and wait for the next call, invoked from my last tx of the 16th byte.

Thank for the support, I'll reply soon with the code.

maui.
