AT#SKTOP AT#SKTOP AT#SKTOP AT#SKTOP Execution command activates the context number 1, proceeds with the
authentication with the user ID and password previously set by #USERID
and #PASSW commands, and opens a socket connection with the host
specified in the #SKTSET command. Eventually, before opening the socket
connection, it issues automatically a DNS query to solve the IP address of
the host name.
If the connection succeeds a CONNECT

Execution command executes a DNS query to solve the host name into an IP
address.
Parameter:
<host name>
<host name> <host name> <host name> - host name, string type.
If the DNS query is successful then the IP address will be reported in the
result code:
#QDNS:"<host name>",<IP address>
#QDNS:"<host name>",<IP address> #QDNS:"<host name>",<IP address>
#QDNS:"<host name>",<IP address>
Note: the command has to activate the GPRS context if it was not previously
activated. In this case the context is deactivated after the DNS query.
Note: <IP address>
<IP address> <IP address> <IP address> is in the format: xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx

set and that the GPRS network is present.
