Perhaps my terminology was wrong, it actually says block-mode.

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.
