If xterm is true vt102 emulation, it will have an answer-back escape
sequence, which is used by some DEC systems to interrogate the terminal
in order to determine special information.  In fact, if memory isn't
playing me false, the vt100 had two interrogation sequences, one for
asking for the terminal's type, the other for getting the user-supplied
answer-back message, no?
