RS232C Communication in VB.NET 2003

[thomasc1020]

Hi,

I am trying to write a code which reads in the iput characters from a
RS232C port(COM port). I found out that 'mscomm' can be used to solve
this problem on VB.NET 2005. However, I was unable to find out any
information about 'mscomm' from msdn that came with my caopy of
VS.NET
and any information on wheher 'mscomm' can be used in VB.NET 2003.
Please let me know how to communicate through a RS232C port in VB.NET
2003.


Thank you very much in advance!

Hi,

You can use MSComm (I have examples in my book, and there is a KB article
that addresses it and other OCXs on msdn.com), or you can download
DesktopSerialIO.dll for 2003 (free) from my web site. It is a .NET dll,
which makes serial IO rather easy. The download includes a simple example.

I have lots more detailed information in my book, and additional examples --
also the source code for DesktopSerialIO.

and any information on wheher 'mscomm' can be used in VB.NET 2003.
