Open a Socket Connection

Question

I have an RFID reader that has an internal memory bank that
stores rfid scans. From speaking to the company in order to get the
data off I need to create a socket connection to port 8080 and send
RQL (which is similar to sql) and then it will send me back piped
results.
Can anyone assist me on how to open a connection to ip
192.168.1.139 port 8080 and send this
SELECT read_count, protocol_id, antenna_id, id FROM tag_id
WHERE protocol_id='GEN2' set time_out=8000
and then output the results it returns.
Thanks in advance!

Thanks for your response, ok i've change the code to use the
following, but now it just hangs... i.e. it looks like it's working
in the browser but then just times out.
<cfsetting requesttimeout="1000">
<cfflush interval="5">
<!-- begin code sample -->
<cfset serverStruct = structNew() />
<!-- the variables -->
<cfset serverStruct.serverIp = "192.168.1.139" />
<cfset serverStruct.serverPort = "8080" />
<cfset serverStruct.portConnected = "" />
<cfset sLines = "">
<!--- Create the socket object --->
<cfset objSocket = CreateObject("java", "java.net.Socket")
/>
<!--- Connect --->
<cftry>
<!--- Set up socket to IP:port of remote server --->
<cfset objSocket.init(serverStruct.serverIp,
serverStruct.serverPort)/>
<cfset serverStruct.portConnected =
objSocket.isConnected()>
<!--- Did we connect? --->
<cfif serverStruct.portConnected>
<!-- create the string. Note the use of quotes to escape
quotes in a string -->
<cfset mySendData = "SELECT id FROM tag_id WHERE
protocol_id='GEN2';">
<!--- obtain the streams --->
<cfset input = objSocket.getInputStream()>
<cfset output = objSocket.getOutputStream()>
<!--- set up buffered reader for the socket; it will read
character data
into a buffer until until enough of it can be processed
efficiently. However,
a buffered reader reads a reader object, hence we first have
to convert the
inputstream into a reader --->
<cfobject class="java.io.BufferedReader" name="brObj"
action="CREATE" type="JAVA">
<cfobject class="java.io.InputStreamReader" name="isrObj"
action="CREATE" type="JAVA">
<cfset streamReader = isrObj.init(input)>
<cfset dataBuffer = brObj.init(streamReader)>
<!--- send the data to the remote server --->
<cfobject class="java.io.PrintStream" name="pwObj"
action="CREATE" type="JAVA">
<cfset writer = pwObj.init(output)>
<cfset sentData = writer.println(mySendData)>
<!--- Get the response from the server --->
<!---<cfset response = dataBuffer.readLine()>
<cfset sLines = "">--->
<cfset sLine = dataBuffer.readLine()>
<cfloop condition="#isDefined('sLine')#">
<cfset sLines = "#sLines##sLine#">
<cfset sLine = dataBuffer.readLine()>
</cfloop>
<!--- Close the streams and the connection --->
<cfset streamReader.close()>
<cfset dataBuffer.close()>
<cfset writer.close()>
<cfset objSocket.close()>
</cfif>
<cfcatch type="any">
something went wrong.
</cfcatch>
</cftry>
