RS232 to Excel

[John Gittins]

How do I write and receive data from RS232? Does XP cause any problems in
this?

Here is some information previously posted by others in response to similar
questions.

The best way to do it is to use the MSComm control that comes with Visual
Basic. If you want to see how this works, load and single step through the
VBTerm sample that comes with it (should be in the \samples subdirectory; if
not, I think you can download it from Microsoft's Visual Basic site).

One important note, though, is that you must know the syntax of the commands
to your meter (or other device), as sent via RS-232. Once you know those
you can simply modify the VBTerm code to suit your own purposes. It's
complex at first, but stick with it!

If you are looking for a good tool to do serial communications
directly from within Excel, I would recommend that you look at a
product called WinWedge at the following URL:
http://www.taltech.com/TALtech_web/products/winwedge.html

WinWedge is designed to make it easy to both send and receive serial
data direclty from within any other Windows program including Excel
and it requires little or no programming at all.
