+IFC Options
+IFC = A
+IFC = A,B
Specifies the flow control to be implemented.
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 remote
modem.
2 Hardware flow control (RTS)
B Specifies the flow control method used by the modem to con-
trol data from the host
0 None
1 Local XON/OFF flow control.
2 Hardware flow control (CTS).
+IPR =
Fixed DTE Rate.
Description
0 Automatically detect the baud rate.
[BPS] The decimal value of the rate in bits per second.
Note that the parameter represents the DTE rate in bps and
may be set to any of the following values: 300, 600, 1200, 2400,
4800, 7200, 9600, 12000, 14400, 19200, 38400, 57600, 115200,
230400, 245760, and 307200.
+ITF Options
+ITF = A
+ITF = A,B
+ITF = A,B,C
Transmit flow control threshold.
A
Threshold above which the modem will generate a flow off
signal
<0 to 511> bytes
B Threshold below which the modem will generate a flow on
signal
<0 to 511> bytes
C Polling interval for indicator
0 to 300 in 10 msec units.
+MR=X
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 as fol-
lows:
+MCR: e.g. +MCR: V32B
+MRR: e.g. +MRR: 14400
