A. Fixing a COM Port Problem. If the MultiVOIP main screen appears but is
grayed out and seems inaccessible, the COM port that was specified for its
communication with the PC is unavailable and must be changed. An error
message will appear.
To change the COM port setting, use the COM Port Setup dialog box,
which is accessible via the keyboard shortcut Ctrl + G or by going to the
Connection pull-down menu and choosing “Settings.” In the “Select Port”
field, select a COM port that is available on the PC. (If no COM ports are
currently available, re-allocate COM port resources in the computer’s MS
Windows operating system to make one available.)
