Function
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)
Function

256-character maximum MNP block size
Send a 1/10 second line break to the modem, where n = 1 to 9.
At normal connect, the default is 3
Set break control, where n= 0 to 2. The effect of this command
depends on the modem operating condition. Default is 1.
