You have an higher priority interrupt pending on the
"kind of" UART. Probably you have had two interrupts
(TxReady and RxFull) on the same IRQ and you have treated
only one of them, or you have forgotten to treat a modem
interrupt or... Look at the UART interrupt priorities
in your documentation.
This is excluding the obvious case "two serial lines shares
the same IRQ".
Hope that helps,
Etienne.
