  • USB tty .init & .lock device nodes?

    From Ted Nolan @21:1/5 to All on Thu May 14 03:04:26 2020
    I just installed a USB/RS232-DB9 cable on one of my FreeBSD boxes for a possible upcoming use. The system recognized it with no problems and
    created device nodes for it:

    crw-rw---- 1 uucp dialer 0x76 May 13 00:15 /dev/cuaU0
    crw-rw---- 1 uucp dialer 0x77 May 13 00:15 /dev/cuaU0.init
    crw-rw---- 1 uucp dialer 0x78 May 13 00:15 /dev/cuaU0.lock
    crw------- 1 root wheel 0x73 May 13 00:15 /dev/ttyU0
    crw------- 1 root wheel 0x74 May 13 00:15 /dev/ttyU0.init
    crw------- 1 root wheel 0x75 May 13 00:15 /dev/ttyU0.lock

    My question is what are the ".init" & ".lock" nodes? A quick look
    at what seemed the relevant man pages didn't turn up anything. My
    plan, if I actually end up doing anything at all, is to ignore them
    and see what happens.

    Are these documented somewhere?

    man uart (I know, not very obvious). Look under te heading 'Special
    devices'.

    Ah, thanks!

    I had tried "man ucom" and "man uftdi"..
