Part 2 – AT Commands for the SocketEthernet IPChapter 8 – General AT Commands for SocketEthernet IP

#IPNETMASK – Set Subnet Mask

Description:

Sets the subnet mask.

 

Note: The module must be reset to put the command into effect.

Syntax:

AT#IPNETMASK="<Subnet Mask value>"

 

AT#IPNETMASK? Read or display the current setting.

Responses:

AT#IPNETMASK = 255.255.255.0 returns and OK

 

AT#NETMASK? returns 255.255.255.0 (Manually Configured) and OK

Values:

IP Address in dotted decimal notation (xxx.xxx.xxx.xxxx). "x" = a number between 0-255.

Default:

255.255.255.0

#DNSSERV1 – Set DNS Server IP Address

Description: In order to translate the server names from literal format into IP addresses, the TCP/IP stack software implements the Domain Name System (DNS) protocol. The DNS Server IP address must be specified for use by the TCP/IP stack software.

Syntax: AT#DNSSERV1="<value>"

AT#DNSSERV1? Read or display the current setting.

Responses: AT# DNSSERV1=192.168.0.1 returns and OK

AT# DNSSERV1? returns 192.168.0.1 and OK

Values: 32-bit number in dotted-decimal notation (i.e., xxx.xxx.xxx.xxx).

Default: 202.56.215.6

#DNSSERV2 – Set Secondary DNS Server

Description: In order to translate the server names from literal format into IP addresses, the TCP/IP stack software implements the Domain Name System (DNS) protocol. The DNS Server IP address has to be specified for use by the TCP/IP stack software. This secondary DNS server is used in the case where the primary DNS server does not respond to a request.

Syntax: AT#DNSSERV2="<value>"

AT#DNSSERV2? Read or display the current setting.

Values: 32-bit number in dotted-decimal notation (i.e., xxx.xxx.xxx.xxx).

Default: 202.56.230.6

Note: The Universal IP resolver (DNS Client) has a list that holds up to 4 DNS servers, the first 2 in the list are populated by the #DNSSERV1 and #DNSSERV2 commands, the 3rd and 4th are populated by DNS information provided by the ISP or cellular carrier. The list is checked in order (1-4). This means that user configured name servers will be checked before dynamically assigned name servers.

#EMACSPD – Set Ethernet Connection

Description: Sets the Ethernet connection at 10 or 100 full or half duplex.

Syntax: AT#EMACSPD=x where x stands for 0,1,2,3,4

Values: 0 – Auto Sensing

1 – 10Mbis half duplex

2 – 10Mbis full duplex

3 – 100Mbis half duplex

4 – 100Mbis full duplex

AT#EMACSPD? View the current setting. Can view with AT#VALL or AT#VIP also.

Default: AT#EMACSPD=0
