Hi
How can I send what I type in a textbox to a serial port has hexadecimal

AA BE 02 80 51 00 00 00 00 00 02 80 08 00 00 00

I want to send the above line to my serial port

Hi,

Here is a (long-hand) way:

Dim Buffer (15) As Byte
Buffer (0) =  &HAA
Buffer (1) = &HBE
Buffer (2) = &H2
Buffer (3) = &H80
Buffer (4) = &H51
Buffer (5) = 0
Buffer (6) = 0
Buffer (7) = 0
Buffer (8) = 0
Buffer (9) = 0
Buffer (10) = &H2
Buffer (11) = &H80
Buffer (12) = &H80
Buffer (13) = 0
Buffer (14) = 0
Buffer (15) = 0

SerialPort.Write(Buffer, 0, Buffer.Length)

BTW, my previous reply assumed VS2005, and System.IO.Ports.  If you are
using VisualStudio 2003, you can download DesktopSerialIO from my homepage.
Create a buffer of hex data (Byte array), and do use the Output method:

Serialport.Output(Buffer)
