Decoding Notes

For both message types the status field is used to set the quality indicator.
For the EM1000 message the quality indicator is set to 1.00 when a 00h byte is encountered and a --1.00 if any other bytes is encountered.
For the EM3000 message the quality indicator is set using the following table:

Drivers IO Notes

Command line parameters "EM1000" and "EM3000" indicate the message type as being decoded.
"OI" indicates that the time tags are obtained from preceding "OiSTAR" headers, if available.
Otherwise the first incoming byte is time tagged.
