I'm working in an aplication for a Smart Device that need to "talk" with a
printer continuosly through the serial port. I'm trying to use the John
Hint's sample code "Use P/Invoke to develop a .NET Base Class Library for
Serial Device Communication" but I'm new with VC# and need some basic rules
because I have a lot of compilation errors.
Where should I create my inherited class?
Thank you

Hi,
every 250 ms (timer event) I must send several commands via serial
port. The serial unit will answer to each command sent. I must wait the
answer before send the next command.
How can I achieve this? I receive the incoming data in the "data
received" event of the serial port. Furthermore I need to manage a
timeout: if I receive no answer within a specified amount of time an
event will be generated.

Hi all,
I'm a newbie in .NET technology.
I've already developed Serial communication applications in C++
(WIN32).
And I wanted to migrate to .NET technology.
There is a serial component in framework to read and write on serial
port.
I would like to make asynchronous reception. I saw that we can pass a
delegate to the serial class which is call when some data is readen on
the port.

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:
