我要把１６进制０２用ＶＢ写出到串口设备，咋办．那位高手给个提示，先谢谢了！

dim Byt as byt
byt=2
.output=byt

dim Byt as byte

朋友,能不能给个完整点的?

找找以前的文章吧

不好意思,上面的有问题!
Private Sub Command1_Click()
Dim Byt(0) As Byte
MSComm1.Settings = "9600,n,8,1"
If MSComm1.PortOpen = False Then
  MSComm1.PortOpen = True
End If
Byt(0) = 2
MSComm1.Output = Byt
End Sub

谢了！

辉哥,不错!本人佩服,佩服.
运行了一下很好,只是想再请教下+十六进制字咋办?

发送确定的数组
Dim OutByte(5) As Byte
 OutByte(0) = 0
 OutByte(1) = 1
 OutByte(2) = 2
 OutByte(3) = 65 'A
 OutByte(4) = 66 'B
 OutByte(5) = 67 'C
 MSComm1.Output = OutByte
