    The reason that you can "lose" interrupts on the PC COM ports is not
    entirely related to the COM port hardware itself. There are some
    BIOS implementations (mostly related to display adapters) that feel
    free to disable interrupts (execuite a CLI instruction) any time
    they want to. 

In the case of most SLIP/PPP drivers, BIOS is circumvented entirely.
