Hi! Im trying to use a line discipline as a way to hook my kernel module up to a serial port. I've implemented methods for open, close, and receive_buf, and registered the line discipline (Im using N_MOUSE as my number for now) I've tried using stty line 2 < /dev/ttyS1 to attach my line discipline to a serial port (and tried this on an already open port too (using cat to open the port) and my methods never get called. I've even written a little userspace program that opens ttyS1 and uses tcsetattr() to select c_line=N_MOUSE. It looks like the ldisc is being set because after this stty reports ttyS1 to be using '2' which is correct, however my methods are still never called. What am I missing?
