dev : uart(4)
Development happens on the uart branch in Perforce. See also http://people.freebsd.org/~marcel/uart.diff
- XXX - The PCI bus attachment calls device_set_desc() with some sensible device card identification string. This is later overwritten by the low-level probe function in uart_dev_ns8250.c with the type of UART. It's probably better to keep the card description. Thus, there needs to be a convenience function that sets the device description only when one is not set. This also implies that uart_bus_probe() should not set the device description first. It should set it last.
- Create per-device sysctl nodes that can be used to query the current state of the UART. This could include the line settings (e.g. baudrate, databits, stopbits and parity) as well as the current modem status (e.g. DTR, DSR, RTS, CTS and DCD signals).
- pc98 support is still not going anywhere.
- It would be nice if uart(4) could support USB based UARTs.
