Hello,
Someone can help me about serial port with C++ .NET (Windows forms
application). Like setting port, opening it, transmiting, receiving,
closing, etc.
Thanks very much (for me and my students)

Hi,
you can open a com port with CreateFile (filename "COM1:") and operate with
normal read and write. I think
it's still the same in .NET.
Bye, Holger.
Or just download ACE (Adaptive Communications Environment)
for free and get a lot more power. :-) -----Original Message----- Hello,

Has that been ported to .NET now?
Thanks,

There is a decent article here: http://msdn.microsoft.com/msdnmag/is...m/default.aspx
The code is in C#, you can convert easily if you must. This basically
accesses the native API's; you have all the "power" you need.

Unfortunately we do not provide any mechanism in the framework to easily
accomplish serialport communication. This is a highly requested feautre and
we are seriously considering it for the next release.
However there is some documentation that might help you. The following has
a few links under the Accessing COM ports from C#/VB.Net that might be
helpfull: http://www.gotdotnet.com/team/csharp/code/default.aspx
This has some samples implementations that you could use: http://www.gotdotnet.com/community/u...x?query=Serial
I have personally used the following sample and it provided all of the
functionality that I needed: http://www.gotdotnet.com/Community/U...mpleGuid=b06e3

Hello to everybody,
I've done an application that draws in a frame the trajectory of a
robot. The robot position is readed through the serial port, and
several commands are wrote through the same port to change the
direction of the robot.
The trajectory frame is managed by an applet, and the project works
good when the applet is called by a html document allocated in the
same local machine under W98 where the classes and the serial port...

I'm writing a driver in Python for an old fashioned piece of serial
equipment. Currently I'm using the USPP serial module. From what I can
see all the serial modules seem to set the timeout when you open a
serial port. This is not what I want to do. I need to change the
timeout each time I do a "read" on the serial port, depending on
which part of the protocol I've got to. Sometimes a return character
is expected within half a second,...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
