Hi all,
I have been working in a diagnostics development for 2.4 & 2.6 Kernels.
I have a specific issue in doing internal loopback in 2.6 kernel. In
2.4 kernels I have used the TIOCMSET ioctl for setting the Modem Control Register (TIOCM_LOOP Bit). But the same doesnt work for 2.6 kernels.
Is there any specific reason for this ?
Also it has been said that in 2.6 kernel they have implemented the function callbacks..instead of ioctls..(But still I can find the ioctl function in the driver)
int (*tiocmget)(struct tty_struct *tty, struct file *file); int (*tiocmset)(struct tty_struct *tty, struct file *file, unsigned int set, unsigned int clear);
How to use these functions from user space ?
Please provide some input on this..
Thanks and Regards, Sudhakar V
