I have an application where there are two NIC interfaces in the computer
- one build in and a add on card.
This is equipment that prints boxes full of apples and pears. The
interface to the Printing System is by 10 meg Net interface. TCP/IP.
The equipment also has a standard NIC 10/100 PCI card installed for
network access and linking multiple Systems together for reporting
functions.
My question is how independent are these Net Interfaces?
And is it possible to be sure that the information for the head is sent
only to the head and not out the other NIC card?
Does the system check both cards while making a connection - - trying to
make connection to the printing system and then after the connection
been made - - never use the other NIC interface.
What I am wanting to make sure is that a customer will not put some
other equipment on the network at the same fixed address of the printing
system and have it effect the printing system link.
If this could be done by locking the our software to one of the NIC
Cards that would be perfect. The only question is how- - - -
I see nothing in the CLient Socket that relates to what NIC card that it
is trying to use.
If this is a Windows setting for the network settings - - which one and
how to tell the client socket which to use?
Thanks Jim P.
