Problem sending Hexadecimal as part of a string using socket.send

[Alpha]

Hi, I'm able to make connection to a server using socket connection.
However, when I send a command string the server just ignores it. All
command string needs to start with "0xF9" at Byte 0. During the run-time
debug, I see it to be "u" with a "~" on top of it. Is that OxF9? Can
someone tell me what I'm doing wrong?
Thanks, Alpha

private void Connect(String server, String message)
{
//Socket Connect
try
{
//create a new client socket ...
m_socClient = new Socket(AddressF amily.InterNetw ork, SocketType.Stre am,
ProtocolType.Tc p);
String szIPSelected = "192.168.1. 7";
String szPort = "22333";
int alPort = System.Convert. ToInt16 (szPort,10);

System.Net.IPAd dress remoteIPAddress =
System.Net.IPAd dress.Parse(szI PSelected);
System.Net.IPEn dPoint remoteEndPoint = new
System.Net.IPEn dPoint(remoteIP Address, alPort);
m_socClient.Con nect(remoteEndP oint);
// String message = "Hello There";
// byte[] byData = System.Text.Enc oding.ASCII.Get Bytes(message);
// m_socClient.Sen d(byData);

}
catch (SocketExceptio n se)
{
MessageBox.Show ( se.Message );

//Send ATS Data

m_socClient.Sen d (byData);
}
catch(SocketExc eption se)
{
MessageBox.Show (se.Message );
}
//Receive ATS Data
// Receive the TcpServer.respo nse.

try
{
byte [] buffer = new byte[256];
int iRx = m_socClient.Rec eive (buffer);
char[] chars = new char[iRx];

MessageBox.Show ("Reply from ATS server: "+ Retmessage.ToSt ring() ,
"ATS Reply", MessageBoxButto ns.OK, MessageBoxIcon. Information);
}

Alpha,

0xF9 is definitely not in the ASCII character set, so it's very possible
that the character you see is correct. However, this doesn't mean that what
you are sending is wrong. It just is that the "u" character is the
representation of that byte. However, how the service interprets it is
completely irrelevant.

If you actually want to send the byte F9, then do not send it as a
string. Rather, create the byte array with this value yourself, and send
that.

Hope this helps.

Thank you Nicholas for the help. Can you show me how to send F9 and the rest
of my message in the bye array?

Thanks, Alpha
