Hello, I am using Visual Studio .Net 2005 beta. I have my computer's two
comm ports connected with a serial cable (and null modem). I'm trying to

in a Hyperterminal window open on comm port 2. Hyperterminal is configured
with the same settings that the port 1 is opened with (see below), but I do
not get an 'a', I get some funky ASCII character that looks like a...

Hi,
I'm experimenting with the Serial Port in VB.NET 2005. Although it isn't
that easy to get any feedback from my COM-port as I thought it would be...
How can I read all the Data that the port sends back?
I tryed with SerialPort1.ReadLine, but that blocks the application and takes
a lot of time (10 seconds!), I tryed SerialPort1.Read, but I have to read it
into a buffer and has to indicate the count, but how do I know this?

Hi,
What is the right way for transmitting data on the serial port of a PC using
VB.NET (under XP) ?
I used to use the ActiveX MSComm under VB6, which becomes obsolete and needs
a certification, only available if Visual Studio 6 is installed.
Thanks for any Help !!!

Hello everyone,
I'm new to visual VB and I am trying to setup communications to the
outside world. I found the example listed below in the help section of
Microsoft Visual Basic 2005 Express Edition. Using the Hyper Terminal
should I be able to see the string "Hello" or am I completely off base
here? Thank you in advance for all and any help.
Best regards, Ken

Hello,
I would like to get some opinions on using the Comm Port with
Access 2000. We have a few jobs coming in that require us to interface
with a PLC via the Comm Port. My partner feels we should use a Visual
Basic Front End and the VB component as opposed to Access.
Has anyone had good luck interfacing to a Comm Port using
Access?

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.
Here is my compilation command:
