Basic AT Command Set (Command Defaults in Bold) (Continued)
Command
+IFC Options
Specifies the flow control to be implemented.
+IFC = A
A
Specifies the flow control method used by the host to control data from the modem.
0 None
1 Local XON/OFF flow control. Does not pass XON/XOFF character to the remot modem.
2 Hardware flow control (RTS).
B
Specifies the flow control method used by the modem to control data from the host.
0 None
1 Local XON/OFF flow control. Does not pass XON/XOFF character to the remot modem.
+IFC = A,B
2 Hardware flow control (CTS).
+ITF Options
Transmit flow control threshold.
+ITF = A
A
Threshold above which the modem will generate a flow off signal.
+ITF = A,B
< 0 to 511> bytes
B
Threshold below which the modem will generate a flow on signal
< 0 to 511> bytes
C
Polling interval for <EM><BNUM> indicator
+ITF = A,B,C
0 to 300 in 10 msec units.
Modulation reporting control.
X
Mode
0
Disabled
1
Enabled
If enabled, the intermediate result code is transmitted at the point during connect negotiation. The
format of this result code is asw follows:
+MCR: <carrier> e.g. +MCR: V32B
+MR = X
+MRR: <rate> e.g. +MRR: 14400
+MS Options
Modulation Selection.
+MS = A
A
Preferred modem carrier
+MS = A,B
V21
ITU-T V.21
+MS = A,B,C
V22
ITU-T V.22
+MS = A,B,C,D
V.22B
ITU-T V.22bis
+MS = A,B,C,D,E
V32
ITU-T V.32 (default for CC-14.4K2)
V.32B
ITU-T V.32bis
V34
ITU-T V.34 (default for CC-33K2)
V90
ITU-T V.90 (default for CC-56K2)
B
Automatic modulation negotiation
0
Disabled
1
Enabled
C,D Min rate/Min rx rate are optional numeric values that specify the lowest value at which the
DCE ma establish a connection. If unspecified (set to zero), the are determined by the carrier and
automode settings.
+MS =
A,B,C,D,E,F
E,F Max rate/Max rx rate are optional numeric values which specify the highest values which
specify the highest value at which the DCE may establish a connection. If unspecified (set to 0),
they are determined by the carrier and automode settings.
