The local xterm is version 372.  Merging the following .Xresources

  > XTerm*VT100.modifyOtherKeys: 1
  > UXTerm*VT100.modifyOtherKeys: 1

does let emacs receive C-, and C-. for icomplete for/backward completes
to work as expected in the xterm.

icomplete-vertical-mode worked because C-n and C-p were received by
emacs in the xterm.

Having in the documentation the need for xterm version 216 or later
with setting "XTerm*VT100.modifyOtherKeys: 1" will help.
