I want to map the function keys on a couple of terminals that have wierd
sequences of characters for their function keys (tvi920 and VT220).
I will use the TVI920 as an example.  Function keys on the 920 send the
sequence "\C-A<letter>\r".  Now I know I can map these keys by defining
a sparce keymap for \C-A, then a sparce keymap for each function key
with \r bound to the function wanted.  Or I can bind the letters in the \C-A
map to functions that gobble up the \r and then invoke the wanted function
with call-interactively.  Either way it takes a lot of set-up and
greatly increases how long emacs takes to come up (which is long enough
already).  What I really want is a way to tell emacs to ignore the
following n characters when even it executes a function for the \C-A keymap.

This whole problem is much worse with the VT220 as it uses the sequence
"\e[<digit><digit>~" so complete binding of the 12 function keys takes
dozens of sparse keymaps or an intrepreter function that duplicates a lot
of the functionallity of keymaps and the command input system.
