Paul Traina	77f77631e7	(a) remove the pointer to each driver's tty structure array from cdevsw ... (b) add a function callback vector to tty drivers that will return a pointer to a valid tty structure based upon a dev_t (c) make syscons structures the same size whether or not APM is enabled so utilities don't crash if NAPM changes (and make the damn kernel compile!) (d) rewrite /dev/snp ioctl interface so that it is device driver and i386 independant	1995-02-25 20:09:44 +00:00
Bruce Evans	ae5e131ac8	Avoid duplicating ttselect() so that we don't have to change cyselect() ... when ttselect() is improved. This requires using an array of tty structs and not using ttymalloc(). Fix an off by 1 error. Some caclulations seem to be off by a factor of NCY. NCY defaults to 16, which gives 256 tty structs occupying 0xd000 bytes. The minor number encoding only allows 16 ttys. Update the types of timeout functions to 2.0.	1995-02-15 18:41:41 +00:00
