IOServiceGetMatchingServices

  • I'm using IOServiceGetMatchingServices to locate the modem device as shown
    in the serial port sample code & the documentation for I/O Kit.

    It works, but it locks up my machine for several seconds with the spinning
    rainbow cursor, and it also slows the mouse movement down to a crawl. Is
    there any way to avoid that effect?

    Is there any other way to find the active modem?
