Description (last modified by mmlr)

TTY Layer

  1. Rework our current TTY layer into a module
  2. Create an API that fulfills the need of a serial port
    • traditional RS232
    • serial over USB.
  3. Integrate the new API into the serial drivers that are already in our repository,
  4. Make sure everything works as expected.
  5. Until now the serial port was reserved for kernel debugging, but it is now time for proper userland support.

Will our tty busmanager be compatible with be's one ?

Component: - Applications → Drivers

If it easily can, I would think it should. But it depends a bit on who is going to work on this, of course :-)

Don't know what a TTY are but there are a component called TTY in tracker. Moving this to that one. This didn't answer my questions. ​http://en.wikipedia.org/wiki/Tty

FreeBSD recently re-wrote their tty system. Is it worthwhile to borrow code from that?

Description: modified (diff)

I've implemented a generic tty module based on the tty driver in hrev39760 and ported over usb_serial to it in hrev39762. The pc_serial (RS232) driver still needs to be ported and the tty driver should now be reworked to use the tty module and only provide the driver specific code that was left out in the generic module. I'm going to work on the tty driver but will leave the pc_serial driver alone. François still wanted to keep backwards compatibility for now and I myself don't have any real serial ports where I could test it on anymore.
