Problems using channel-attached 3270 terminal

I have a couple of 3270-mode terminals locally attached via a 3174-21L on my z890 running Debian/Squeeze in an LPAR.

According to the 3270 terminal driver documentation, I should be able to enter ctrl-C, ctrl-D, etc, using ^C or ^D. I can successfully do this from the SE/HMC console window.

Of course, a locally attached 3270 terminal (I've used a 3279 and 3483 InfoWindow II) doesn't seem to be able to generate a proper character code for "^", so I have attempted and failed to get the "�" character (shift-6 on a 3270 keyboard) recognised as a "^".

I tried modifying the kernel source (defkeymap.map and ctrlchar.c under drivers/s390/char/), and also using dumpkeys/loadkeys to view and modify the keymap at runtime.

According to dumpkeys, the only compose sequenses by default are "^" "z" -> "\000". I used loadkeys to load my modified keymap, which included the default compose sequences, along with versions modified to use "�" instead of "^", but it still didn't seem to make any difference.

Does anyone have any suggestions?
