串口通信问题
用VB串口通信，将发实的两个字符转成16进制的一条指令，程序怎样写，高手指点，谢

[解决办法]
所谓16进制发送实质是2进制发送，适用N字节长文本。

VB code

Private Sub Command1_Click()    Dim sTemp As String    sTemp = "AB" '电子"    Dim yTemp() As Byte    yTemp = StrConv(sTemp, vbFromUnicode)    MSComm1.Output = yTempEnd SubPrivate Sub Form_Load()    MSComm1.CommPort = 1    MSComm1.InBufferSize = 1024    MSComm1.OutBufferSize = 512    MSComm1.Settings = "9600,n,8,1"    MSComm1.PortOpen = TrueEnd Sub
