Can I use LabWindows TCP to communicate with a dedicated port while accessing the network on another port?

[rezlab]

I've been tasked with determining if we can send/receive (at high speed) data packets from one processor to another using the LabWindows 5.5 TCP software to configure a dedicated port. At the same time we need to have a connection to our ethernet network with DHCP. I've looked through current discussions but didn't find exactly this type of question. Any help will be greatly appreciated. Thanks.

Hello,
If you are trying to send/receive raw packets through Ethernet, the best way to accomplish it would be to use a third party library, like Wsock32.lib, which is a protocol-independent interface for network programming. Our TCP functions are high level, and does not let you do such a low level manipulation.

BTW, if you want to use SDK functions in CVI, please check out the KnowledgeBase:

The link below you suggested for using SDK functions no longer exists. Is there
another one?

I don't think we want to send the data over the ethernet connection, we just want to be able to set up the data communication on a separate port of a regular computer that is already connected to our network (for accessibility by other computers on the network). Please let me know if I am misunderstanding about the purpose of this "port" usage and if you have a link to some further info that explains it, even better. Thanks.

How would you use this third party library?
