I'm not familliar with ISDN, They don't have dialtones?

Ok, You probably didn't get a dialtone because of the ATM3.
M3 Normally turns the speaker off during handshaking and dialing.
Try it with M1 and L3 (ATM1L3)
M1 = Speaker controll. (Normal hayes)
L3 = Volume controll. (Normal hayes)

Yes, You are right, This method does work better if you have a
phone line with dialtone attached. :) But not needed!

I just tried it on 7 different brands of modems, All of them
returned OK from AT with ATE0 set. So for these seven brands/models.
AT should prove success or failure.

Yea, I agree, Try several different tests.. :)
Can't hurt.

99.999% of my experiance is Dos based. So I have no idea what
-clocal does. You can bet I'm looking though.. :)

-Enjoy
