Or use 'less' for something a little more interactive: dmesg |less then you can use all the vi-style motion and search commands like G - go to end b - backwards page ?pattern - search backwards etc. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Of course first I tried dmesg, and had to go through lots of output until the last lines said it is indeed ttyUSB0. Then I tried 'ls /dev/tty*' and there it was too.

You'll have to look in /var/log/messages (or run dmesg) to see what HAL / the USB Hotplug deamons mapped it to (at least that is what I would do). I know that a USB printer shows up as /dev/usb/lp. -- Robert Heller -- 978-544-6933 Deepwoods Software-- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows hel...@deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/ ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Terminal emulation and serial ports
I have to reinit a firewall that can only be done from its console port, and I do not have an XP system with Hyperterminal on it. So I went through the archive and learned that minicom could do the job for me. I installed it and went to configure it (minicom -s). I can set the speeds, but the challenge is selecting the serial device. I have a Serial-to-USB dongle, and when I connect it, the gnome hardware browser is showing a FIDI usb serial converter that was not there before connecting the dongle. But what /dev/thingee do I put into the minicom configuration? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
