+MS Select Modulation/Rate
72
how often the DCE reports to the DTE the number of octets in this buffer.
This parameter is ignored in Direct and Synchronous Modes where flow control is not used.
The Off and On parameters are applicable in Synchronous Access, Frame Tunneling, Buffered
V.14, and error control modes. The Report Period parameter is applicable only in Synchronous
Access mode.
The command format for AT+ITF is:
+ITF? Returns current setting.
+ITF=?Returns command range(s).
AT+ITF=<off>,<on>,<report_period>
<on threshold>
<off threshold>
<report period>
<minimum rate>
<maximum rate>
+MS?Returns Current Setting
+MS=?Returns Command Range(s)
The command format for AT+MS is:
AT+MS = <mod>,<automode>,<minimum rate>,<maximum rate> [CR]
(Omitted values remain at the current setting.)
<mod> specifies the PREFERRED modulation as per the list below. Either verbose or numeric
<mod> selections can be used, but verbose settings are reported.
<mod> <mod>
Numeric Verbose
0 V21
1 V22
2 V22B
10 to 759 bytes
11 to 760 bytes
Ø - Disables transmit level reporting
5 to 100 Delay (in 10ms units) between transmit
buffer level reports while in V.80 Sync Access
mode.
Sets the lowest carrier rate that may be used.
(Default 300 bps).
Sets the maximum carrier rate that may be used.
(Default 33,600 bps) Setting a non-zero value in the
S37 command adjusts the +MS rate commands as
well.
