The character sequence should follow ANSI X3.64, meaning that it begins
with an ESC character and continues through an alpha.  That can be
parsed without any timeouts at all.

What probably is contributing to the confusion is that you bought
keyboards that have an ESC key the user can press that violates the
X3.64 standard.  Remove the key or tell your users how to recover
from it (treating a second consecutive ESC specially is one way).
