Communicating between two Computer via USB

[McCloud]

Hello,

I want to connect two PCs to synchronize two different LabView VIs running on these Computers.

The perfect way would be, that the VI on PC 1 sends boolean Value to the VI on PC 2, where this value is read out and can start some process.

My Problem is that I do not have a 'normal' network and all serial Ports (but not USB) are occupied.

I would appreciate any advice or suggestion.

One of my ideas is going in the direction of an USB to 9pin serial Adapter plus a null modem adapter/cable. But I have no Idea if this would work.

I would suggest USB-Ethernet adapters and an Ethernet cross-over cable.

The communications between computers will be faster, and you can use your software across a larger network later on without modifications (just change IP addresses).  Your communications will be message based rather than character based, so you won't have to constantly poll the RS232 port for characters.
