RS232C Packet Loss

Thank you dsl,

I do continuesly throw commands,

but always wait until the board returns "packet received" before throwing the next.

And the command length is only 32bytes.

Is this really a rx fifo matter?..sorry if i'm asking something dum..

..And I can't find fifo length setting in altera_avalon_uart from SOPC..

What I do in my isr is, transferring data

from internal to external RAM

using double buffering without a DMA.

I guess this is taking too much time(?)
