This object is used by an asynchronous user to change the 'com' message for Incoming calls to a string of up to 20 characters. If user selects the value xxx for this object, the PAD will convert it to the relevant X.25 address, followed by CR LF COM (Carriage-Return, Line-Feed, com). Example: 'called by XXX' will be converted to 'called by <X.25 address> com'.
