+                        This command enables V.110 protocol with 9600 baud
+                        (x=9600), 19200 baud (x=19200) or 38400 baud
+                        (x=38400). A value of x=0 disables V.110 switching
+                        back to default X.75. This command sets the following
+                        Registers:

+                            There is _NO_ common convention for 38400 baud.
+                            The value 198 is choosen arbitrarily. Users
+                            _MUST_ negotiate this value before establishing
