So, If I would want to implement a driver, which exposes some fake character devices such as /dev/fake[0,1,2] and every write on such a character device, I would want to send it out to UART, and when the data comes back [receive_buf?], I intrepret the header and copy it onto the relevant buffer of character device fake[0,1,2]. If such a driver has to be implemented, PLEASE SUGGEST AS TO WHAT SORT OF A DRIVER SHOULD IT BE ? Currently I have thought of it as a line discipline driver, can it be any other sort of a driver ? [PTY sort of driver, or something which isn't even dependent on TTY layer?] Because I see that the serial-core and the TTY aren't seperate, every UART driver [say 8250, mcf_serial] also gets registered as a tty driver because it did an uart_register.... Any help is appreciaated... regards, Pavan --- On Wed, 30/9/09, Pavan Savoy <pavan_savoy@xxxxxxxxxxx> wrote: > From: Pavan Savoy <pavan_savoy@xxxxxxxxxxx> > Subject: Re: sharing UART > To: linux-serial@xxxxxxxxxxxxxxx > Date: Wednesday, 30 September, 2009, 6:22 PM > Hi, > > So is it confirmed that no one as of now, had to use 1 UART > for 2 purposes? > That is, say the UART had switch between working as a > normal TTY and also as a Line discipline ? > > No one had to send modem commands and some unique > manufacturer specific commands to modem @ the same time ? > > regards, > Pavan > > > --- On Thu, 17/9/09, Pavan Savoy <pavan_savoy@xxxxxxxxxxx> > wrote: > > > From: Pavan Savoy <pavan_savoy@xxxxxxxxxxx> > > Subject: sharing UART > > To: linux-serial@xxxxxxxxxxxxxxx > > Date: Thursday, 17 September, 2009, 12:46 PM > > Hi, > > I have searched through the archives, but did not find > any > > example or need to share a UART by 2 drivers. > > > > Basically there is a "hci_ldisc" line discipline > driver > > which makes use of the UART which will be followed up > by > > another driver with normal char dev exposed to > user-space > > which needs to make use of UART as well. > > > > So some-one somewhere would have wanted such an > > implementation right ? > > what should be done ? any suggestions are welcome. > > > > regards, > > Pavan > > > > > > > > Add whatever you love to the Yahoo! > > India homepage.
