Mark, thanks. As there are no other votes, I choose line discipline. Generic form of required userspace support is already provided with util-linux-ng and it seems much better to use established low level driver code than reinvent a new one ;). I hope there will be no problem getting a new line discipline registered with include/linux/tty.h, even if it turns out that the code using it is dedicated to a specific device not found on any other board than my Amstrad E3.
