#LEGACYMODE – Legacy Mode Enable/Disable
About Legacy Mode:
Note:
This command is for all devices except the SocketEthernet IP (MT100SEM-IP)
Legacy mode allows for smoother transition to TCP/IP based connectivity from standard analog
interface connections.
When #LEGACYMODE=1, the stack will be in pseudo legacy mode where the commands &S,
&D, &C, A, D, S0, E, V operate independently of the stack. The commands will be saved to a
different NVRAM location and will not affect the IP stack once legacy mode has been exited.
Once in legacy mode, the user can configure the #TCP values and issue an ATD command to
make a connection to the remote host. If necessary, the user can also issue
ATDxxxxxxxxxxxxppppp where x is the decimal address and ppppp is the remote port. The stack
will perform the physical connection and present the user with the proper messages:
interface connections.

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
#RESET – Reset Main Processor or Internal Modem
Description:
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.
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.

#SHIELDCHAR – Configure the Shielding Character for DLEMODE
Description:
This parameter defines the shield character for the clients that use shielding (also known as DLE
shielding with regards to UIP).
shielding with regards to UIP).
Note:
This command is for all devices except the SocketWireless Wi-Fi (MT810SWM-IP)
Syntax:
AT#SHIELDCHAR=[<parameter1>]
AT#SHIELDCHAR?
Values:
0-255 (an integer value between 0 and 255)
Responses:
\r\n#SHIELDCHAR: VALUE\r\n
\r\nOK\r\n
\r\nERROR\r\n
\r\nOK\r\n
\r\nERROR\r\n
Examples:
send: AT#SHIELDCHAR=20\r
reply: \r\nOK\r\n
send: AT#SHIELDCHAR?\r
reply: \r\n#SHIELDCHAR: 20\r\n
reply: \r\nOK\r\n
