TCP Network Programming

[Brian]

Can anyone help me to understand how to make VB .NET transmit text entered in
a text box through a serial port while providing the user with the ability to
select baud rate, parity, data bits, stop bits and comm port used from combo
boxes?

Programming against the serial port just came up today in this group. .NET
doesn't support it natively very well.

Once suggestion was to use 3rd party control from:

http://www.sax.net/framework/communications/

It was then mentioned a free scaled down version was included in VB resource
kit:

http://msdn.microsoft.com/vbasic/vbrkit/default.aspx

Not sure what you can or can't do with this control, but looks like a good
starting point.

Good luck,
Greg

hmmm, not sure how this applies to TCP Network programming - since your
question is really about serial port io... But, the answer is you'll need
to find a 3rd party library to access the serial port, because until 2.0 -
the .NET framework does not support serial communications.

here is an article from msdn magazine that might help you:

The code, is in C# - but the principals are the same.

sending data through a serial port is not using TCP/IP networking.. but if
your search google for RS232 and VB.NET together you will find a lot of info

Brian,

Do not forget to look at everything Richard Grier wrote about RS232 in the
Dotnet newsgroups. (I think there is much more I only selected on RS232).
You will find his homepage than as well.

I hope this helps?

Hi,

This question doesn't have anything to do with TCP/IP or networking.

There are lots of serial classes and add-ons online, or you can P/Invoke the
underlying Windows serial APIs. I have example code for several methods in
my book (see below), along with other example code. You can download
NETcomm ocx from my homepage, or use other ActiveX controls.

There is a serial class in the free Visual Basic .NET Resource Kit that you
can download from Microsoft, or order on CD-ROM for the cost of the
shipping.
