Model 3830 AT Commands

%Bn  Modulation and Data Rate

Sets the modulation and maximum VF rate.

The %B300 and %B1200 commands work in conjunction with the B (ITU-T/ Bell Mode) command to determine modulation.

%B19200	V.32terbo, maximum rate 19,200 bps
%B16800	V.32terbo, maximum rate 16,800 bps
%B14400	V.32bis, maximum rate 14,400 bps
%B12000	V.32bis, maximum rate 12,000 bps
%B9600	V.32bis/V.32, maximum rate 9600 bps
%B7200	V.32bis, maximum rate 7200 bps
%B4800	V.32bis/V.32, maximum rate 4800 bps
%B2400	V.22bis. maximum rate 2400 bps
%B1200	V.22 or Bell 212A, maximum rate 1200 bps
%B300	V.21 or Bell 103, maximum rate 300 bps

Modulation and Data Rate can also be set using S-register S41. The following table shows the equivalent values of S41 for each %Bn value, and, where applicable, %Bn in combination with Bn.

S41	= 20	%B19200	V.32terbo, 19,200 bps
S41	= 21	%B16800	V.32terbo, 16,800 bps
S41	= 1	%B14400	V.32bis, 14,400 bps
S41	= 2	%B12000	V.32bis, 12,000 bps
S41	= 3	%B9600	V.32bis/V.32, 9600 bps
S41	= 4	%B7200	V.32bis, 7200 bps
S41	= 5	%B4800	V.32bis/V.32, 4800 bps
S41	= 6	%B2400	V.22bis. 2400 bps
S41	= 7	%B1200/B0	V.22, 1200 bps
S41	= 8	%B1200/B1	Bell 212A, 1200 bps
S41	= 10	%B300/B0	V.21, 300 bps
S41	= 11	%B300/B1	Bell 103J, 300 bps

The factory default is %B19200.
