Socket Open - #SKTOP
#SKTOP - Socket Open
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
indication is sent, otherwise a
ERROR
indication is sent.
AT#SKTOP=?
Test command returns the
OK
result code.
Example AT#SKTOP
..GPRS context activation, authentication and socket open..
CONNECT
Note
This command is obsolete. It’s suggested to use the couple
#SGACT
and
#SO
instead of it.
3.5.5.1.70.
Query DNS - #QDNS
#QDNS - Query DNS
AT#QDNS=
[<host name>]
Execution command executes a DNS query to solve the host name into an IP
address.
Parameter:
<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>
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>
is in the format:
xxx.xxx.xxx.xxx
AT#QDNS=?
Test command returns the
OK
result code.
