Example. |
|
| |
|
Dim i as Byte
For i = 1 to 20
If Comm1.putByte( i ) = False Then
'// no more room in tx buffer
Exit For
End If
Next i
'// This example will attempt to send the values 1 to 20
'// This function sends the byte as a raw byte value. Not as a string/character. Use this function to send byte values in the range 0 to 255
You do NOT need to change the OutputMode property. The putByte function ALWAYS sends the raw byte value. |
