I suppose this is a classical case of YMMV: I just tried it out (on a BSD/OS box, thus the different device name. On FreeBSD I just have ISDN connections). $ cu -s 38400 -l /dev/tty01 Connected. at OK atm3 OK atl3 OK atdt NO CARRIER ate0 OK OK OK at OK And yes, I got a click from the speaker. But I didn't get a dial tone, for some reason, just a disconnect tone after a while. The trouble with this method is that it requires you to have a dial tone. On the other hand, I'm prepared to accept that not all modems will still generate an OK when ate0 is set, so you'll probably have to try a number of these methods. But you can be pretty sure that nothing is getting to the modem in the first place if you have -clocal set. Greg
