Not sure I follow.  You are talking about a malicious device that
performs bus-mastering accesses before the OS has initialized the IOMMU?

I remember only setting LANG for screen and clearing TERMCAP for irssi,
the latter only being relevant for irssi-colors:

   irssi_su LANG=en_US.UTF-8 /usr/pkg/bin/screen -S irssi -d -m -e^Yy \
sh -c \"TERMCAP= exec /usr/pkg/bin/irssi --home=/data/irssi\"

   (irssi_su being something like `su irssi -c')


That's remote NetBSD-6 and local GNU/Linux.

I recently got all of this working thanks to:
http://docs.perl6.org/language/unicode_entry

and settings in my terminal (osx)
advanced -> text encoding -> utf-8
my lang:
~ $ echo $LANG
en_US.UTF-8

(that's local and remote after ssh)


in screenrc:
defutf8 on
utf8 on

/SET term_charset utf-8 in irssi

start screen with -U

and now I can finally use perl6 characters in irc. «like this»

I always created them on Linux since I did expect fewer problems then.  
Actually I never had problems beside severe performance issues.  But this may 
now have changed significantly because of disabling the atime update.

But thanks for the tip, I'll create them on NetBSD next time.  Maybe this also 
improves performance.

just write a two-line perl script, then. :)

Just googling and reading.

One example: http://www.thinkwiki.org/wiki/Wireless_WAN_Adapters

> Can you provide details about your working PCIe cards?

I have the Ericsson F3507g and the Sierra Wireless EM7345. Both work
well with NetBSD in my experience. I use both on ThinkPad laptops they
were intended for (X301 and T440s respectively). Even these laptops may
require a BIOS update to recognize them though.

Unexpected error while trying to mount ext2fs

[Carsten Kunze]

Hello,

I have a USB flash drive with ext2fs as second and third MBR slice (no slice 1 
and 4 exists).  Slice 2 and 3 are mapped to partition sd0e and sd0f.  When I 
try to mount partition sd0e I get an unexpected error:

# disklabel sd0 
# /dev/rsd0d:

What does "no match" and "no such process" mean?  It did work when there had 
only been sd0e.  Now sd0f is added "below" (note the offset) sd0e.  Maybe this 
causes issues?

Try to obtain more information about the card you can get:
- is it exposing a USB device? (my PCI express cards do)
- in turn, is it exposing a serial port?

Reading through some (Linux) forums may help obtaining this information.

If the answer is yes for both questions, then it should work with
pppd(8) as usual. Then you may also find comms/deforaos-phone useful if
you need a GUI.

Otherwise, YMMV. Sometimes it's just a matter of registering a device in
the kernel; or it's a lot more work and a new driver is required.

A copy of man majordomo is here, & answers half your question:

http://www.berklix.org/help/majordomo/majordomo.txt

"Unsubscribe yourself (or address if specified) from the
named list.  If list  is ``*'' (an asterisk), unsubscribe
from all lists on this Major- domo server."
