Hi, Richard
As to /dev/3270/tub* being block devices, that's new to me. Could you
point me more exactly to where you saw this?
The 3270 driver uses two major numbers, 227 and 228, for line-mode and
fullscreen operations. Both are character devices. The script
/usr/src/linux{,-2.4}/Documentation/s390/config3270.sh generates
/tmp/mkdev3270, which generates character device special files
/dev/3270/ttyfoo and /dev/3270/tubfoo respectively, foo a 4-character
device address. Minor number 0 is used only with major 228 and defines
the generic fullscreen device /dev/3270/tub; 0 is not used with major 227.
To find for yourself what devices the 3270 driver knows about, give
these two commands:
echo what=config > /proc/tty/driver/tty3270
cat /proc/tty/driver/tty3270
Use the address at the CONSOLE line for your console device. The line
will read:
<device> CONSOLE <minor>
If you use the above scripts to configure your 3270s, you should expect
to see /dev/3270/tub<device> as major 228, minor <minor>.
If you don't want to, or don't have them available, do this:
mkdir /dev/3270
mknod /dev/3270/tub<device> c 228 <minor>
Hope this helps.

Are you saying my device should be tub0700 rather than tty0700?
I looked at the device list on kernel.org and saw that /dev/3270/tty* is a
character device and /dev/3270/tub* is a block device.

Mark, you might want to make a note of this and get back with
the rest of the Slack team. Richard H., I haven't looked at
the 3270 console code, but are you okay with 5,1? It is the
current choice for /dev/console, per the kernel doc.

Hi, Richard et al
Major/minor 5,1 for /dev/console seems okay, but I'd be surprised if you
are able to use /dev/tty with that; I bet "echo foo > /dev/tty" fails.
To run ned nevertheless on a 3270 console, use the undocumented -T
option. For instance, if your console's at 0009, use "ned -T
/dev/3270/tub0009". Ordinarily ned uses /dev/3270/tub, the full-screen
analogue of /dev/tty.
handy hint --> Note that, unlike vi, ned can be used at the end of a
pipe: "ps -ef | ned -T /dev/3270/tub0009". <-- handy hint
