Command	Function
+MS=a,b,c,e,f	Select modulation where: a=0, 1, 2, 3, 9, 10, 11, 12, 56, 64, 69; b=0-1; c=300-56000;
	d=300- 56000; e=0-1; and f=0-1.A, b, c, d, e, f default=12, 1, 300, 56000, 0, 0.
	Parameter ″a″ specifies the modulation protocol desired where: 0=V.21, 1=V.22,
	2=V.22bis, 3=V.23, 9=V.32, 10=V.32bis, 11=V.34, 12=V.90,K56Flex,V.34......,56=K 56Flex,
	V.90,V.34......, 64=Bell 103, and 69=Bell 212. Parameter ″b″ specifies automode
	operations where: 0=automode disabled, 1= automode enabled with V.8/V.32 Annex
	A. Parameter ″c″ specifies the minimum connection data rate (300- 56000). Parameter
	″d″ specifies the maximum connection rate (300-56000); Parameter ″e″ specifies the
	codec type (0= Law, and 1=A-Law). Parameter ″f″ specifies ″robbed bit″ signaling
	detection (0=detection disabled 1=detection enabled)
