That would waste fewer minors, too. Yes, this is entirely true. I am thinking about this more from an administrative point of view, I suppose.... but then again, how do you deal with the case where somebody has installed com1/com2 as tty00-01 minor #s 0,1 BB2016 as tty10-1f minor #s 2-17 and then decides to install com3/4 as tty02-03? With the recent minor number range expansion, maybe it would make sense to assign something like 64 or 256 ports per letter, and just be done with it all...? tty00-01 minor #s 0,1 tty10-13 minor #s 256-259 tty20-23 minor #s 512-515 etc That way when somebody replaces a 4 port card with a 16 port card, there are no device names and minors to be shuffled. I don't really know from a kernel point of view how "wasteful" this is, but it would be really nice to see an easily manageable setup for serial ports. > I like the upper-lower distinction for dialin/dialout ports, myself, and it > makes things nice for PS and friends.
