Hayes implemented a "guard" ... they required a pause between the "+++"

out the requirement for the pause.  So, on lots of non-Hayes modems, you
could get them to hang up by just sending that string as data (or
including it as data in a ping packet).

And another cool trick (implemented by the software, not the modem), was

(Yes, I used to enjoy picking on DOS users, and still do.)

Yet another (and very old) one:

During IRC chat session, change your nick to COM1 (or COM2,3,4,
depending on which port the victim has the modem installed). 

Then, ask him/her to send you a private message...

Used to work in mirc+Win95/98, if I remember well...
