Need some help on VB....

can anybody suggest me how to interface hyper terminal to VB?
actually i m controlling four stepper motors through PC.... i need to send commands to uC 8051 :
@APC***- for Auto mode Previous Channel(motor),
@ANC***- for Auto mode Next Channel(motor) etc.....

i did all the programming in C for that... but i want to add a command button instead of wrinting these commands in hyper terminal... how can i do that?

use c# and drag and drop Text box and also drag and drop button too double click draged button and write

SerialPort.Write(TextBox1.Text);

this will send the command written in text box

Private Sub Command1_Click()
MSComm1.Output = "@ANC***"
End Sub

Private Sub Command2_Click()
MSComm1.Output = "@APC***"
End Sub

Private Sub Command3_Click()
End
End Sub

Private Sub Form_Load()
MSComm1.CommPort = 1                    'Define COM port available on PC
MSComm1.Settings = "9600, N, 8, 1"      '9600 Baudrate, No Parity, 8 bits data, 1 Stopbit.
MSComm1.InputLen = 1                    'Read 1 character/byte whenever Input property is used.
MSComm1.InputMode = comInputModeBinary  'Input will retrieve data in array of bytes.
MSComm1.PortOpen = True                 'Open Serial Port COM1.
End Sub

Private Sub MSComm1_OnComm()

End Sub

Private Sub Text1_Change()

End Sub

how can i display same things as in hyper terminal in text1 box.....?

whatever you receive on serial port.. add it to text box

text1.text = "Text to display in text box"

'to update text box
Text1.text = Text1.text & "New Text"
