Yes, this is an ancient and bogus convention which will wreck havoc in a number of surprising ports of broken. >The initial state devices or equivalent functionalty are more important >than the cua devices IMO. If it is possible to set cua behaviour using stty (on the initial state device) cua devices would be unnecessary and should probably be avoided. >Appart from this, all devices on device driver foo should be named >foo<number>, and no driver names should be longer than "foo". While 17576 device drivers would be enough for some time, I am not sure we have the necessary mechanics to control or enforce them being unique and I resist having to come up with a bogus TLA name for a device in the cases where the vendor has already established a perfectly good bogus name of a diffrent length for their device. See for instance sys/dev/musycc -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
