Topic: Invalid Port Number (8002)
|
| By: Yosi Karl | Posted on: Mar 2 2013 at 12:45:30 AM | Hello,
I am trying to use SComm32 from Excel 2007 on Windows 7 (64 bit).
(no issue with multiple licenses, as this project is only intended to run on my computer - if it eventually works).
I follow the pattern of the example:
* Created a form (UserForm1).
* Placed an SComm32 control on the form, called it SComm1
Running the following code:
UserForm1.SComm1.CommPort = 7
MsgBox("Port Name: " & UserForm1.SComm1.CommName)
UserForm1.SComm1.Settings = "9600,n,8,1"
UserForm1.SComm1.PortOpen = True
The Message Box correctly shows the user readable name of the port (""). This means that I set the correct CommPort.
However, when reaching the '.PortOpen = true' command, I receive a run time error 8002.
Anyone can help explain what the problem might be? | |

It returns and empty string "" if the port does NOT exist.
Look in device manager. What ports do you have? | |

The message box DOES show the correct CommName ("USB Serial Port (COM7)") - I made a mistake in my previous post when I wrote an empty string.
The port is also listed correctly in device manager.
Any other ideas? | |
