I have some experience programming in C on microcontrollers. On an upcoming project, I will be outputting data from the micro via UART. Someone else will write a Visual Basic program to read this data and display it on a PC. It will be a while before this program is ready. Before this is done, is there a way I can capture my data and look at it from the PC side, via something like Notepad, for instance? How do I go about doing this? Writing to a file and looking at it later is OK too. Thanks. Shaker

Hi Try this one: www.docklight.de I think this is the most suitable RS232 monitor program I have sen until now. Best regards Jens "V.

I typically used RealTerm: http://realterm.sourceforge.net/#Installing "Tal" sells a product, that will allow you to aquire serial data in any application, Word, Excel...etc. http://www.taltech.com/products/winwedge.html On 7 Mar 2004 03:41:28 -0800, shakervc@yahoo.com (V.

For example, perhaps 0x10 (the "0x" prefix means hex) will return status information. Perhaps 0x11 will change the status information. You can use terminal programs like HyperTer, that comes with Windows, to send commands and receive the data. The only problem is that sending hex directly from HyperTerm is not supported the last time I checked. So, what you may want to do is provide an interface that is character based. For example, '1' to get the status, '2' to update the status, along with the status data. This is something that HyperTerm can do, then it can save to file. Hope this helps you. If not, let me know and I can try again. Dennis, -- If sending a reply you will need to remove "7UP".

Hyperterminal is usable when you've got nothing else, but a few second's google searching will show dozens of freely available terminal programs that are far better in every way. "Tera Term Pro" is great for most tasks, while "RealTerm" is has more advanced features. There are also plenty of commercial programs with even more functionality, for those that need it. Using Hyperterminal for testing serial communications is like using Notepad for editing code. It's better than nothing, but there are more alternatives than you can count (and even more opinions as to which is best :-), and when you find one you like you will not regret the time spend checking out the tools.

(In my defense: I used to use Procomm, and later Terminate, under DOS. Nowadays I tend to use Hyperterminal a) because it's there b) because my serial comms needs are far more modest than they were and c) because that's what my customers use, so I have to be able to support it. Mostly, however, I write my own.) Steve http://www.fivetrees.com http://www.sfdesign.co.uk

We solved the short term need by going out to eBay and buying about 40 old 486 laptops, all the same model, and run PROCOMM+ under DOS on all of them. This was a cheap remedy from the viewpoint of cost, but was time consuming. (Great project for a part time student) It does however, solve our serial testing needs for the next few years. They aren't elegant, but they make a great tool. When a tool works, you really don't have any imperative to replace it. When was the last time you upgraded your hammer to 1/4 inch nutdriver?
