That is correct.

Actually, I'm writing a script that will be used for other connections
as well, and using wpa_supplicant for all of them simplifies the writing
of the script.  Although I was doing all of this manually for the purpose
of demonstration, I felt it would be best to reproduce what the script
does as nearly as possible.  Once I get it working without WPA or WEP, I
will be working on getting it to also work with them on other networks.

Yes, it appears that since Slackware 12.1 has the hostap drivers
blacklisted by default, the orinoco driver was the first to load, and
/lib/udev/write_net_rules automatically added the following lines to
/etc/udev/rules.d/70-persistent-net.rules:

# PCMCIA device 0x0002:0x0156 (orinoco_cs)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:05:5d:d6:43:20", ATTR{type}=="1", NAME="eth1"

Once I get the hostap driver working, I will delete those lines and use
the name the hostap driver creates.  For now, I'll leave it as is.

I noticed that I already did that in the script, but failed to do it
when I did it manually.  The result is the same, however, I noticed
that ifconfig shows "RUNNING" before that command, and doesn't show it
after.  Do you have any idea why that would be?

Yes, the script was originally set up to use the hostap driver, and
since it worked without changing it with the orinoco driver, I left it
as is so I wouldn't have to keep changing it depending on which driver
was loaded.  I used the command as it appears in the script so you would
be able to see exactly what the script was doing, and what was and wasn't
working.  Sorry for not explaining that before.

Here is the results of using the iwconfig command to set the mode and
show the results:

Does that tell you anything?  The card is in managed mode for sure but
ifconfig doesn't say "RUNNING" for that interface.
