<?LassoScript
Variable: 'Connection' = (Net);
$Connection->(Connect: 'www.example.com', '80');
...
$Connection->Close;
?>
No Parameters Required.

Use the [Net] type and its member tags to establish a TCP connection. The following example opens a blocking TCP connection to the Web server running on an example server and fetches the root document. The result will be an HTML page.
[Variable: 'myConnection' = (Net)]
[$myConnection->(SetBlocking: True)]
[$myConnection->(SetType: Net_TypeTCP)]
[Var: 'Result' = $myConnection->(Connect: 'www.example.com', 80)]
[Fail_If: $Result != Net_ConnectOK, (-1), 'TCP Error']
[Variable: 'Result' = $myConnection->(Write: 'GET /\r\n')]
[Variable: 'Output' = $myConnection->(Read: 32768)]
[$myConnection->(Close)]
[Output: $Output]
