Conexão adodb com SQL Server

[Edson David <edsondavidp@xxxxxxxxxxxx>]

Guys, I'm trying to make the connection to the SQL Server database using adodb, but when I run the lines below, the page is blank, not returning any rows. The problem from what I dectetei, is when the connection attempt is made ​​with the server and the table data. 
Thank you in advance.

<?php
// Include the library
include('adodb/adodb.inc.php');
$conn = &ADONewConnection('mssql');
$conn->Connect('192.168.1.2:1433','','','siscom'); // Connection to the database
$sql = "SELECT * FROM agenda"; // Select the table columns calendar
$consulta = $conn->Execute($sql);
// Displaying Data
echo("<table width='250' border='1'>
        <tr>
            <td>ID</td>
            <td>Name</td>
        </tr>");

while(!$query->EOF) {
    echo("<tr>
            <td>" . $query->fields[0] . "</td>
            <td>" . $query->fields[1] . "</td>
          </tr>");
    $query->MoveNext(); 
}

// Number of table records 
$tot_register = $consulta->RecordCount();
echo("<tr><td colspan='2'> Total record (s): " . $tot_register . "</td></tr>");
echo("</table>");
