 Modem Permissions I have Slackware 10.2 with 2.6.17.4 kernel. My computer has a Conexant hsf modem that is driven by Linuxant. The modem permissions are crw-rw---- 1 root:root 240, 64 < date is boot time > /dev/ttySHSF0. I try to reset this to crw-rw-rw- 1 root:tty 240, 64 but every time I boot it resets. I would like to set this permanently so that every user in group tty can use the modem. Can anyone help with this? Bob      |

If you're using udev, try this: udevinfo -q path -n /dev/ttySHSF0 That will output something like: /class/tty/ttySHSF0 Now do this (substitute the last string for whatever outputs previously): udevinfo -q all -a -p /class/tty/ttySHSF0 Have a look at the portion of the output that starts with this: looking at device '/class/tty/ttySHSF0': and consider making a custom udev rule (to set group ownership and or device permissions) using that information. If you need help with making a udev rule, come back and post that last bit of info I advised on using to make the rule, and we'll go from there. RW -- http://rlworkman.net |

Well, call me weird, but I actually *like* udev... Of course, I must admit that I like it a lot better now than I did back in when 10.2 was released - it's matured quite a bit since then...
