You've pretty much summed it up - DEC vt200- and vt300-series ttys use
the LK-201 keyboard.  One "feature" of this keyboard is that ESC (F11)
sends a known character sequence, which you described, above.
DEC-designed O/Ss (ie, VMS) know about this, since they only support
DEC ttys.  I use a vt320 at home, and get around this by just using
ctrl-[ intead of F11/"ESC".  The only alternative I can think of is to
program the key on the terminal to actually send the 0x1B character
(ESC).  I wrote a utility to do this once, but it was lost long ago.
It's a royal pain-in-the-butt to program them, but if there is enough
interest, I'll rewrite it with a nice interface.
