For the byte-synchronous controller, the bits of the status word that are equal to 1 can
be interpreted as follows:
If modem loss was detected or, for a read unit, if a vertical redundancy check error was
reported, bits 8 through 15 of the status word have the following meanings:
. 7 Data set ready sensed
. 8 Channel parity error
. 9 Channel abort
. 10 Character overrun
. 11 Device parity error
. 12 Byte count termination
. 13 ETX compare
. 14 Character compare
. 15 Break
Bit Meaning (Write Unit) Meaning (Read Unit)
. 0 Power on Power on
. 1 Channel underrun Device overrun
. 2 Channel abort Channel abort
. 3 Channel parity error Unused
. 4 Auto poll terminated Block-check character error
. 5 Data set ready terminated Vertical redundancy check error
