Re: [ECOS] IO serial block transfer

["David Airlie" <David dot Airlie at parthus dot com>]

the interrupts are HW dependant not software .. the block transfer just
speeds up the software...

Does your serial device have a FIFO ... have you enabled it .. how deep is
it enabled.. these all control the interrupt levels...

the 16x5x driver should have FIFO control in it for the RX direction
(never got around to TX)...
