To change the COM port setting for the 3Com® PCI 56K modem, modify the registry:
Before performing the steps below, try setting the communication software to COM 3.
This article describes how to change the COM port setting for 3Com PCI 56K modems (Controller based modem). Currently, neither the 3Com control panel nor the modem icon within the Microsoft® Windows® Control Panel provide a way to change the COM port setting. As long as the IRQ used by the modem does not conflict with another device, you should not need to change the IRQ. Even though IRQs were once hard-coded to certain COM ports with legacy ISA modems, they are no longer. You may need to change the COM port setting when a communication program is unable to address the modem on what used to be a non-standard port, such as COM 5. Before performing the steps below, try setting the communication software to COM 3. If this does not help, then try the below procedure to change the COM port in the registry.
