There are PCI cards that allow multiple concurrent serial connections. Does the Proxy show a single COM connection or multiple connections?
A. The PCI card should have a driver that sets up the registry to show the different COM ports. ConnectProxy looks in the registry and uses the Win32 API to create a file with the COM port. So in theory, ConnectProxy supports multiple simultaneous COM port connections. In this case, even though all the COM ports would be sharing an interrupt request line (IRQ), performance should not be an issue.
