Description: If legacy mode is enabled, the AT interface tries to behave like a legacy analog modem. ATD and
ATA will function on the TCP stack instead of the physical connection. Responses will behave like
that of an analog modem.
Syntax: Set Value: AT#LEGACYMODE=1
View Values: AT#LEGACYMODE?
Values: 0 Disable legacy mode
1 Enable legacy mode
Default: 0
#PERSISTENTSOCKET - Persistent Socket
Definition: If enabled and the physical connection is present, a socket will be created automatically.
Note: This command is for all devices except the SocketEthernet IP (MT100SEM-IP).
Syntax: Set Value: AT#PERSISTENTSOCKET=<Persistentsocket value>,<Result Codes>
View Values: AT#PERSISTENTSOCKET? or AT#VALL
Values: 0 Persistent socket is disabled
1 The TCP originate is started (#OTCP=1)
2 The TCP listener is started (#LTCPSTART=1)
3 The UDP originate is started (#OUDP=1)
4 The UDP listener is started (#LUDPSTART=1)
Result Codes: 0 All result codes will be suppressed during socket connection/disconnection
1 All result codes will be displayed during socket connection/disconnection

#RESET – Reset Main Processor or Internal Modem
Definition: This command will force a reset on the Stack and internal radio or just the internal radio.
Syntax: AT#RESET =<value>
Values: 0 Reset the Stack and internal modem
1 Reset the internal modem only. Note: This value is not valid for the SocketEthernet IP
(MT100SEM-IP) and the SocketWireless Wi-Fi (MT810SWM-IP)
Example: AT#RESET=0
Note: After issuing AT#RESET, it can take up to 45 seconds before the MT810SWM-IP is ready to
accept AT Commands. When configuring the MT810SWM-IP using security mode WPA or
WPA2, the bootup time will take longer.
