The bad news: the N800 emulation is faithful to the real hardware to the point thaaaat I... cannot type. Yippee.

So, I made this:

done

I spent about 10 minutes figuring out the X,Y coordinates of all of the "keys" in the osso-xterm on-screen keyboard, and put them into the above shell script that pecks away at the OSK with the mouse for me as I type normally. With the (necessary) delays it's a bit like semi-remote SSH.

It uses xinput as a keylogger and xdotool to move and click the mouse. (Use it with a text editor or a terminal running cat focused, since sending the Enter key into the QEMU window will switch you to full-screen keyboard mode.)

This only allows me to type basic commands, though. I do NOT want to eg add the routines to handle uppercase letters or special characters etc etc unless I absolutely HAVE to...

Oh - and this is for a US keyboard layout, you'd have to go look at xmodmap -pk if you're on a different layout (I forgot where I put my code that parses xmodmap output and didn't feel like rewriting it so just left it with the fixed keycodes.)

(One last thing, leave it running and try and type elsewhere

the result is hilariously disorientating

)

Even more bad news: I don't have any networking!! I'm not sure what options to pass to get this working - if there are any. :/

(As an aside, ping appears to not have been made suid root. Nice one.)
