Excel Vba Serial Port ProgrammingHere is some information I have collected in the past. Never had a personal need to use it: mscomm control =================== posted by eric in programming In the VBE, create a userform. Next, create a communications control (Microsoft Communications Control, version x.x) and name it Comm1. In the properties window of the communications control, see what the name is. Micromax software upgrade. When they put together their own IOS, it is referred to as a custom Internal Operating System (cIOS). These cIOS files are often built up from official IOS files and then installed as a new file, on your Wii they will always simply be labeled as an IOS. Hackers of the Wii will utilize and modify the functionality of the official IOS files to their own end. Waninkoko originally modified IOS36 and installed it as IOS249. IOS36, IOS37, and IOS38 are official IOS files which are generally installed by Nintendo onto your Wii system. Developer ZoneSerial COM port development for Windows using Visual Basic for Applications. Using ActiveXperts Serial Port Component with VBA (Visual Basic for Applications). ActiveXperts Serial Port. You can edit the visual basic code behind your form in Excel by clicking the button 'View code' View code below 'Design mode' on. Therefore not as widely available as Excel. Fortunately, sample VBA code has been developed and freely distributed that uses the Windows API to perform the I/O operations. The code that was found at several sites online18 was created for up to four serial ports and 32-bit systems – and therefore not compatible with 64-bit. See, I made a joke at work about this not being what Excel should be able to do, and how even Emacs can't access the serial port. Except it can. Gonna have to be more careful with the Emacs irony. ' Communications port settings. ' Assuming that a mouse is attached to COM1, CommPort is set to 2 MSComm1.CommPort = 1 MSComm1.Settings = '9600,N,8,1' ' Open the communications port. On Error Resume Next MSComm1.PortOpen = True If Err Then MsgBox 'COM1: not available. Change the CommPort property to another. We'll name this one comExcel for the examples below. Then in a module, type: Comm1.comExcel.CommPort = [Enter the com port here] Comm1.comExcel.Settings = '9600,n,8,1' 'enter your own for your device Comm1.comExcel.PortOpen = True 'opens the port Comm1.comExcel.Output = anything that needs to read from the computer to the PC Use at your own risk!!!! This code works for our weight scales, but you'll have to read your manual to get the output you desire. If anyone has any other suggestions, please feel free. ---------------------------------- Thomas Lutz Unfortunately Excel makes it almost impossible to do serial communications directly using VBA. Fortunately there are other easy solutions for inputting serial data into Excel from devices like scales, measuring tools and bar code readers. The company that I work for sells a serial communications program called the Software Wedge that you may find to be a good tool for adding serial communications capabilities to your application. The Software Wedge is an executable program that can pass serial data back and forth to other programs using either DDE (Dynamic Data Exchange) or by converting incoming serial data to keystrokes (i.e. It stuffs the keyboard buffer with the incoming serial data). The program is extremely easy to use and is designed to have you up and running sending and receiving serial data directly from within your application in just a few minutes.

Regards, Tom Ogilvy ================== From: 'Jack Silver' Newsgroups: microsoft.public.excel.programテつュming Subject: Re: RS232 communication in excel Date: Thu, 5 Oct 2000 19:32:17 -0400 Organization: Photon Technology International Lines: 61 ====================== There are a few ways to do this. If the instrument provides data on its own (such as a lab balance or bar code reader), you may consider software wedge (see ). This reads the serial port, and data is entered into Excel as if it was entered into the keyboard (in fact, it pushes data into the keyboard buffer).
