No, you can have only up to NR_LDISCS ldiscs in the system and you have to choose one of them to "handle" a particular tty. IOW, you register an ldisc which is available for everybody then. And it cannot have ->private_data since everybody would share this single ->private_data. Instead everybody comes with their devices as ttys which have ->private_data for everybody's data and ->disc_data for you to note anything about the (tty) device. Am I missing something? regards, -- js _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
