Hi,

These are two different issues. For serial communications, you use the
Windows serial communications APIs. This may be done by using a .NET class
that wraps the functionality of these APIs using Platform Invoke. I have
example code in my book (see below), and there are several examples
available online, both for VB and C# (example, www.msdn.microsoft.com and
search for 101 VB.NET examples). Or, you can use an ActiveX control, like
the free NETComm.ocx that you can download from my homepage. Lastly, there
is at least one commercial comms product for .NET (go to www.saxsoft.net for
this).

For parallel IO, the only way is to use a kernel-mode device driver. There
are no methods built into Windows for this. To make is easy, you can
download IOocx.ocx from my homepage.

C++ getting data from serial/parallel port, how to?

by: Sonoman | last post by:

Hi all: I tried searching on the net, but I do not even know what I am looking for. What I want to do is to write aprogram using C++ that will gather data from an external microprocessor, format it and write it to a file for later use. I can handle pretty much everything exept the part where I "listen" to either the serial or parallel (may be USB?) ports for data from the external source. Any help will be greatly appreciated.
