<userIpType> parameter is only valid when <IPaddr> is domain name and
dual stack connection is open by #SGACT.
When <userIpType> is "no ip type chosen" ipv6 will be requested firstly.
When ipv6 DNS server does not support so ipv4 will be requested.
<closureType> parameter is valid for TCP connections only and has no
effect (if used) for UDP connections.
<lPort> parameter is valid for UDP connections only and has no effect (if
used) for TCP connections
If we set <connMode> to online mode connection and the command is
successful we enter in online data mode and we see the intermediate
result code CONNECT. After the CONNECT we can suspend the direct
interface to the socket connection (N.B. the socket stays open) using the
escape sequence (+++): the module moves back to command mode and we
receive the final result code OK after the suspension.
After such a suspension, it is possible to resume it in every moment (unless
the socket inactivity timer timeouts, see #SCFG) by using the
#SO command with the corresponding <connId>.
If we set <connMode> to command mode connection and the command is
successful, the socket is opened, and we remain in command mode and we
see the result code OK.
If there are input data arrived through a connected socket and not yet read
because the module entered command mode before reading them (after an
escape sequence or after #SD has been issued with <connMode> set to
command mode connection), these data are buffered and we receive the
SRING URC (SRING presentation format depends on the last
#SCFGEXT setting); it is possible to read these data afterwards issuing
#SRECV. Under the same hypotheses it is possible to send data while in
command mode issuing #SSEND.
<txTime> parameter is valid for UDP connections only and has no effect (if
used) for TCP connections. For slow servers it is recommended to adjust
