I have a quick question on interrelationships between the ioctl() routine in a driver, and the routine thats in the t_param field of the tty structure. I believe I read someplace (correct me if I'm wrong), that the kernel, upon sensing an ioctl() call that COULD change line parameters, would call the routine specified in t_param on the ioctl()'s completion. >From what I can see, this is not the case. I may be wrong. I hope I'm wrong. But, right now I'm seeing baud rate changes that aren't being set on the hardware. Can someone clairfy this for me, or just tell me I was dreaming when I read about this? (It is possible...) :) -Brian
