(ATE0 or 1, echo off or on) Although no matter what ATE is, It still should echo OK by entering AT if it's working. Typing ATDT should result in a dial tone if plugged into phone line. As stated earlier, I prefer to use ATDT it can be heard! What do you get when you type: # cu -l cuaa4 Connected. AT <enter> (Should result a: OK ) ATDT <enter> (Should result a: dialtone if pluged to a phone line) Unless of course it's broke. :) Did you make your device files after compiling/installing/re-booting you system?? -Enjoy Gary ~~~~~~~~~~~~~~~~ Improve America's Knowledge...
