SocketModem Global MT5634SMI Developer’s Guide 32
Command: %Sn Command Speed Response
Values: n = 0, 1
Default: 0
Description: %S0 Sets modem to respond to AT commands at all normal speeds.
%S1 AT commands accepted at 115200 bps only. Commands at other speeds are ignored.
Command: $Dn DTR Dialing
Values: n = 0 or 1
Default: 0
Description: $D0 Disables DTR dialing.
$D1 Dials the number in memory location 0 when DTR goes high.
Command: $EBn Asynchronous Word Length
Values: n = 0 or 1
Default: 0
Description: $EB0 Enables 10-bit mode.
$EB1 Enables 11-bit mode.
Command: $MBn Online BPS Speed
Values: n = speed in bits per second
Default: 28,800
Description: $MB75 Selects CCITT V.23 mode
$MB300 Selects 300 bps on-line
$MB1200 Selects 1200 bps on-line
$MB2400 Selects 2400 bps on-line
$MB4800 Selects 4800 bps on-line
$MB9600 Selects 9600 bps on-line
$MB14400 Selects 14400 bps on-line
$MB19200 Selects 19200 bps on-line
$MB28800 Selects 28800 bps on-line
$MB33600 Selects 33600 bps on-line
Command: $RPn Ring Priority vs. AT Command Priority
Values: n = 0 or 1
Default: 1
Description: $RP0 The AT command will have priority over the ring. S1 will be reset to 0 if an
AT command is received. This command is storable to memory.
$RP1 The ring will have priority over the AT command. S1 will increment even if an
AT command and ring are received together and the incoming call will be
answered when S1 is equal to S0.
Note: SocketModems do not detect ring cadence of TelTone telephone line
simulators as a valid ring.
