As I mentioned, I suspect this sort of thing was inherited from Unix practice, back when serial ports were common.
In the reply from Stefan you can see that this is an openSUSE specific thing that had been done because someone with two (or more) multiport cards complained about missing OOTB support. Has nothing to do with unix history. The vanilla kernel default still seems to be 4 or 8.
Also, how much in the way of resources does this consume?
None. Did I complain about resources? I don't want to kick out serial support, I don't want to reduce CONFIG_SERIAL_8250_NR_UARTS (increasing that was well sensible). I want a sort-of clean /dev directory that doesn't list too much useless stuff. Or do you want to get rid of udev and get back to a static /dev that just has everything that could ever be used?
BTW, I just looked at my system and see 64 tty and 32 ttyS listed. How much memory, CPU, etc., do they consume, if not connected to anything?
And now you connect a serial-to-USB converter, and fire up some Windows program via wine that needs to talk to the device connected there. And you have to guess which of the 33 COM devices offered is the correct one.... -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
