The FIFO is enabled.When I get a RDA IRQ I read 14 bytes (FIFO threshold). When I get a CTI I read until the LSR0-bit is cleared. Maybee I should try the same loop when I get the RDA IRQ to be sure there aren't another full FIFO? If that's the case, shouldn't that generate another pending RDA IRQ? /PH
