Scott Duensing eebcf100ad Fix hard lockup on COM port open from stale UART interrupt
Clear IER and read IIR/LSR/MSR/RBR before hookIsr unmasks the PIC.
A pending interrupt from a previous session would fire immediately,
but the ISR skipped dispatch (isOpen still FALSE), leaving the IRQ
asserted on level-triggered ISA -- infinite ISR loop.
