Note: VTS also includes a Modem Tools library that contains modem diagnostics tools. The Modem Tools library enables you to draw a modem Event Log Button (which is a list that VTS automatically updates with modem event information), a Save Log Button (which saves the modem event log to a text file), and a Modem Statistics Panel (that displays the number of lines available, the number of lines used, the total number of calls, the number of failed calls, and the total call delay in seconds).
