We have an NT 4.0 workstation that we have installed an ASUS COM ISDN PCI card.<br><br>We have it dialing the internet for ftp files and the logon and users settings should have it disconnect after 15 seconds of non use.<br><br>The line stays up until manually hung up.<br><br>Does anyone have any ideas or dos utilities that would hang up the line?<br><br>thanks<br>Joe
