Very old technology.Army telephones in 1941 had a buzzer and a morse key
so that the operator could send morse code over the telephone. The problem
was that the signals radiated from the telephone line and could be
picked up over a range of some hundred yards or so and so the enemy could
read it. We therefore used Fullerphones over telephone lines for morse
code. They were dessicated DC which was rectified in the machine at the
other end and could be read throough phones. It did not radiate frm the
telephone cable and so was secure.
Dessicated DC = interrupted DC Warren in case you didn't get it!!!

FAX and Morse code, interesting. Have you tried sending CW over the
telephone?
That would be an interesting QSO, gives DTMF a whole new application!
