I cannnot communicate w/ the gvmu w/ a direct connection from my serial port. I have a usb to serial connection, pptc9, and then 3 pair cable to the admin port on the voice mail and all i get is bad handshakes or the screen says stratagy not running or modem not responding. Is it a bad pin out or settings on my comp. I know the serial port is good b/c i use it w/ other voice mails. I do have the xadmn4 software installed.
