trying to do a mini "hyperterm" like test applet for my boss (more proof of concept than anything) and i'm having problems utilizing SerialSession, here's what I have embedded into my form. basically I want to send command from the text box, and show what's currently being seen from the unit in the RTFbox.

{
public partial class Form1 : Form
{
SerialSession RS232 = new SerialSession("COM1");
public Form1()
{
try
{
RS232.AnyCharacterReceived +=
new SerialSessionEventHandler(RS232_AnyCharacterReceived);
RS232.BaudRate = 9600;
InitializeComponent();
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
}
void RS232_AnyCharacterReceived(object sender, SerialSessionEventArgs e)
{
try
{
richTextBox1.Text += RS232.ReadString();
}
catch (Exception exc)
{
MessageBox.Show(exc.Message);
}
}
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
try
{
if (e.KeyCode == Keys.Enter)
{
RS232.Write(textBox1.Text);
textBox1.Text =
"";
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
}
}
