Wrong!  A 1670 can detect No Dial Tone, Busy, Ringing, and Voice, but only 
after you type ATX2.  You can use this with DesTerm by changing the X1 in
the initial modem sequence to X2.  Also, if you use Kermit, you can type
ATX2DT <phone #>, and it will redial the number up to about 10 times or until 
you get through (if the system you are calling is busy).  This means you don't 
have to type A/ every time you want to redial.
