Corey Minyard ad4c2aa635 Serial 8250: handle saving the clear-on-read bits from the LSR and MSR ... Reading the LSR clears the break, parity, frame error, and overrun bits in the 8250 chip, but these are not being saved in all places that read the LSR. Same goes for the MSR delta bits. Save the LSR bits off whenever the lsr is read so they can be handled later in the receive routine. Save the MSR bits to be handled in the modem status routine. Also, clear the stored bits and clear the interrupt registers before enabling interrupts, to avoid handling old values of the stored bits in the interrupt routines.
