packages/devs/serial/generic/16x5x/current: ChangeLog
packages/devs/serial/generic/16x5x/current/cdl:
ser_generic_16x5x.cdl
packages/devs/serial/generic/16x5x/current/src: ser_16x5x.c
Log message:
* 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).
