| |
Hi all .
I am working on serial communication protocol for an x86 industrial platform , namely Advantech PCM 5825 CPU board + PCM 3618 RS232/485 communication board. Tried 2.4.33 and 2.6.18...20 kernels .
After investigating some incoming data corruption I noticed that sometimes the status value that has been read from LSR contains the "FIFO error" bit set ( 0x80 ) . I did not find a code that handle this condition , there is no even such bit mask defined in serial_reg.h . BTW I have this bit set even if all other error bits in LSR are 0 ( frame error etc.) . Is there any reason for not to handle the "FIFO error " bit ? Or it is just because the situation is very rare ?
Any comments appreciated . Thanks . - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
