+MS=m (Modulation
Control)
The +MS command controls the modulation used on a
connection. It also controls whether or not automode is
used, as well as the maximum and minimum carrier
data rates (line speed) on the connection. Default is
+MS=V.34B, 1, 0, 0;B1.
+MS=<carrier>,<automode>,<min rate>, <max rate>;Bn
Valid carrier parameters are: V34B, V34BS, V34, V34S,
V32B, V32, V22B, V22C, V22, V21.
V34BS and V34S parameters set symmetrical line rates
for both transmit and receive. V34B and V34 allow for
asymmetrical data rates on transmit and receive. V34B
or V34BS is for 33600 to 2400. V34 or V34S is for
28800 to 2400. V32B is for 14400 to 7200. V32 is for
9600 and 4800. V22B is for 2400 and 1200. V22 is for
1200. V21 is for 300.
Automode allows the modem to find the highest
common speed for each connection given the line
conditions encountered by the modem. This parameter
is also controlled by the Nn command. 0 is automode
disabled and 1 is automode enabled.
The minimum line rate parameter specifies the lowest
data rate at which the modem will establish a
connection. Allowable parameters are: 33600, 31200,
28800, 26400, 24000, 21600, 19200, 16800, 14400,
12000, 9600, 7200, 4800, 2400, 1200 and 300. A
setting of 0 is the same as the lowest setting for any
given modulation method.
