+       * cdl/ser_generic_16x5x.cdl
+       (CYGINT_IO_SERIAL_GENERIC_16X5X_CHAN_INTPRIO): New interface
+       for devices that support per channel interrupt priorities.
+       
+       * src/ser_16x5x.c Added int_prio to pc_serial_info type.
+       serial_config_port(): uses macro
+       CYG_IO_SERIAL_GENERIC_16X5X_CHAN_BAUD_GENERATOR() to get the baud
+       devisor from platform if device suppports per channel baudrate
+       clocks, pc_serial_init(): Use interrupt priority from int_prio
+       data field if device implements
+       CYGINT_IO_SERIAL_GENERIC_16X5X_CHAN_INTPRIO

+       (CYGPKG_IO_SERIAL_GENERIC_16X5X_XMIT_REQUIRE_PRIME): New option.
+
+       * src/ser_16x5x.c (pc_serial_start_xmit): Allow platform to define
+       CYGPKG_IO_SERIAL_GENERIC_16X5X_XMIT_REQUIRE_PRIME if enabling THRE
+       interrupt does not generate interrupt unless bytes are posted to the
+       FIFO.

+
+       * src/ser_16x5x.c (serial_config_port): Add
+       CYGPRI_IO_SERIAL_GENERIC_16X5X_PLF_INIT_HOOK
+        in case devices need extra initialization.

+       * cdl/ser_generic_16x5x.cdl
+       (CYGNUM_IO_SERIAL_GENERIC_16X5X_FIFO_TX_SIZE): New option.
+
+       * src/ser_16x5x.c (serial_config_port, pc_serial_putc,
+       pc_serial_DSR): At TX interrupt, write up to
+       CYGNUM_IO_SERIAL_GENERIC_16X5X_FIFO_TX_SIZE bytes to the transmit
+       FIFO. This makes better use of the FIFO, since the LSR_THE flag
+       resets when the FIFO is non-empty (not when it's full, as this
+       code previously assumed).

        * src/ser_16x5x.c (pc_serial_init): 
-       Allow platform to define CYG_IO_SERIAL_GENERIC_16X5X_BAUD_GENERATOR if the
-       baud rate clock (values) cannot be known at compile time.  In this case,
-       the baud rate generator values are provided by platform specific code,
-       computed when the device is first initialized.
