Speed delection in call and answer mode.
~ | (Same as for +M1, but the aulomatic speed
"= detection is also active when the modem is
operating as originator of a connection.)
"if the remote modem is preset for dialling with automatic
transfer rate detection, it may happen that the modems
will be connected at another transfer speed than defined
in the communications programs. To avoid this, it is
advisable to set one of the modems to a fixed rate.
This speed detection applies to V.32 bis, V.32, V.22 bis,
V.21 and V.23. The interworking between V.32 and V.22
bis is according to the recommendation of ITU.-T.
+&M Selects standard for 111 control
Commands: +&M0 , +&M1, +&M2, +&M3
A » én | Selects V.32 standard, i.e. low rate is 4800
+ ae : :
AT &MO | | bps and high rate is 9600 bps
: M1 poten Selects V.22 bis standard, i.e. low rate is 1200
2 & fa '[bps and high rate is 2400 bps
AT+&M 2p - | Selects V.22 standard, ie. low rate is 600 bps
and high rate is 1200 bps.
+ M p= Selects V.32 bis standard, i.e. tow rate is 7200
AT &M3 a bps and high rate is 14400 bps
The +8M2 and the +&M3 commands should only be used for
speed selection with V.24 ct111.
\N Set Operating Mode
Commands: \NO, \N1,\N2, \N3, \N4, \N5, \N6, \N7
The modem has a full duplex error correcting protocol
implemented according to ITU-T V.42 (LAPM and MNP level 2
through 4). With block transmission and retransmission on
receivers request, V. 42 is only used for asynchronous DTE's.
ATINOE Normal mode
e Buffered mode with speed conversion capabilities
e Flow control (XON/XOFF) can be used (\Q-command).
e Password/Dialback can be used.
e Inactivity timer (+S8) can be used.
e No protocol support.
