Modem information B-9
Detail for +MS Controls
An example of a command is AT+MS = V90, 1, 24000, 33600, 28000, 56000
+MS=<carrier>,<automode>,<min transmit rate>,<max transmit rate>,<min receive
rate>,<max receive rate>
<carrier>= B103 for Bell 103 (300 bps)
B212 for Bell 212 (1200 bps)
V21 for V.21 (300 bps)
V22 for V.22 (1200 bps)
V22B for V.22bis (1200-2400 bps)
V23C for V.23
V32 for V.32 (4800 & 9600 bps)
V32B for V.32bis (7200, 12000, 14400 bps)
V34 for V.34 (2400-33600 bps)
K56 for K56flex (28000-56000 bps)
V90 for V.90 (28000-56000 bps)
<automode> = 0 (for automode OFF)
= 1 (for automode ON)
<min transmit rate> = 300 bps to 33600 bps
<max transmit rate> = 300 bps to 33600 bps
<min receive rate> = 300 bps to 33600 bps
<max receive rate> = 300 bps to 56000 bps
