Read Link Test Status of TP Ports
The link test status of all eight TP ports can be read using this command. Bits 0 through 7 correspond
to the link test status of TP ports 0 through 7. A "1" on the MSO bit indicates "Link Good" status and a
"0" indicates "Link Fail" status.
Read Polarity Status of TP Ports
The polarity status of all eight TP ports can be read using this command. Bits 0 through 7 correspond
to the polarity status of TP ports 0 through 7. A "1" on the MSO bit indicates reversed polarity and a
"0" indicates positive polarity.
Read Partition Status of TP Ports
The partition status of all eight TP ports can be read using this command. Bits 0
through 7 correspond to the polarity status of TP ports 0 through 7. A "1" on the MSO
bit indicates a connected status and a "0" indicates a partitioned status.
