Accessing SERIAL Port from Excel VBA
The purpose of this article is to demonstrate how you can perform serial port communication in the VBA Visual Basic Applications — script editor included in any typical Microsoft Excel distribution but without using the MSComm control or any other third party add-on or ActiveX. In order to get access to the VBA script editor, you first need to make the corresponding buttons available on the Excel toolbars they are not there by default.
These buttons will enable you to launch the editor in which you will be able to write the Visual Basic Code and will also allow you to directly create windows-style controls like textboxes, push buttons, labels, radio buttons, checkboxes etc.
In order to make these available on the main toolbar, you need to activate the Control Toolbox button, from the small toolbar activated at the previous step. As a goal for this article, I would intend to demonstrate how you open the serial port, how you write a few bytes, how you read some bytes, and then how you close the serial port. In order to do all these, you will need to create four windows-style buttons, each of them performing one of the tasks that I have enumerated before.
Click on the Command Button control from the recently activated toolbar, and then draw 4 similar buttons anywhere on the surface of your excel worksheet figure 1. Figure 1: Command button for a version of excel Once you did that, click on the Visual Basic Editor button from the toolbar that you activated in the very first place.
This will open the environment in which you can write the code for the Visual Basic scripts that will perform the operations you wanted.
Once there, make sure that you double click on the Sheet1 Sheet1 entry. The effect of this action will be the opening in the main window of this environment of the actual sheet in which you will write the VB code.
Once you reached this stage, copy paste the code below in there. The comments in the code are self. Submit Comment. The character LCDs are the most commonly used display modules.

I was hoping I could run this outside of a Dev environment as well.

I have manage to find a solution that actually works. However there is a problem that I would with it that I cannot understand: the macro to list connected devices seems to be able to detect up to COM9.
COM10 and above is not listed. Anyone have any ideas why? Thanks in advance. How many COM ports does your computer have? I always expect the student to do their homework and find all the errrors I leeve in.
Please take the time to read the Forum FAQ. Hello s.
This call is limited by the string convention used for identifying the COM port. Not sure why this is but I suspect it is a throwback to the early days of computing.
Here is the updated line of code Hello Leith Thank you for your input. The solution you provide worked brilliantly! I haven't written any code for COM ports in about 15 years. Thanks for posting this code. It is very a comprehensive and flexible approach to programming the ports. Brilliant piece of work by the original author.
Love you. Originally Posted by s.

This script interface has following features: - Scripts can send and receive data with the main interface Serial Port Notifier formerly Serial Port Monitor sits in your notification tray and monitors the serial ports on your computer. When a port is added or removed, a notification is shown containing the port's COM port name, allowing you to easily keep track of what's been plugged in and out.
Program launchers can be defined that allow programs to be quickly started using the selected serial port. Custom labels can also be added to ports to allow for easy identification. Real Time Electronic Circuit Simulator. Requires Visual Studio. NET 4 or Xamarin Studio to compile.

We are sorry. Erick Wagner. Leave a Reply Cancel reply. You've already signed up, Thanks!XXX as an integer which is the temperature and it is working no prob as I mentioned the problem is the first time excel wants to communicate and open the port there is nothing happening the instrument has been connected to PC true RSUSB adapter and the OS is windows 8 I wonder if there is any command that I have to send at the beginning to kind of clear the pathway or not?
Hi TNX for the code but unfortunately it did not work!!!
Use Open to connect to serial port
Hi iliagod First can you please read the forum rules and add code tags around you code in the previous post. I've read the manual and there a a few things to try. Thanks mate it is working, I need to test it more at the moment, but it is cool, I need to find out how the code works and how I should feed my code to it the com selection is not working it is not show any thing.
I can not use it to download but again when i open and close the port with this one you send me after that my code is working i have to find out what you did to open and clear the pathway for the comport again I appreciate the time you put to answer me.
Hi me again I was wondering if it is possible to do the same thing true the network connection Same instrument with same commands all I need to do is send it to the IP address do you know what will be the format of command?
Is it possible to use this Excel to connect to 2 or more instrument of the same type? Sorry for thread digging figured it would be worth the shot for some help. Dear Kristan Is it possible to use this Excel to connect to 2 or more instrument of the same type? Hi I use this sub to control my Serial instrument and it is working ok Code.

Re: Use Open to connect to serial port let me know what help you need. Re: Use Open to connect to serial port hi is there version of this that work sheet that works for both 32bit and 64bit regards sheldon. Re: Use Open to connect to serial port Hmm not that I think of.
Regards Kristian. Re: Use Open to connect to serial port You should post a question in the forum but Code. Quote from Kristian. Hello, Unfortunately, Not that I know of. So sad!!How to go about doing this? I am required to write a set of macros which will output a set of random strings to COM Port and use this to test an equipment.
I am successful in creating the set of random commands. I don't know how to connect to Serial port. Yes, it can be done.
You used to be able to use the dos COPY command to copy to a device. Generating a batch file is relatively easy. First off though If you choose to try this It should read something like There is a dll available on the net called inpout Is there something for this.
It is transparent, the system sees it as another comm port. I have neen doing it for several years now. Something about not being licenced or approved. They may be large!! My method has one module with very good comments and was written by someone who knew what he was doing.
Hi Muriel Dunn, Would you mind sharing the excel workbook as I am trying to do the same thing. Hope with your excel workbook, I can communicate with the device on the com port and send Hex strings. Hi Muriel, Simmilarly can you share the workbook?
