8.3.1 SAP Receive Buffers
Whenever a SAP is updated, the scanner fills in the appropriate receive buffer
in the M1 file. Some of the data comes from the source station; some comes
from the scanner.
Bit 7 in Status is set if the SAP is operating with no problems. If this bit is 0,
there is a problem with this SAP.
If there is a problem with this SAP, Error contains the value 1.
SrcStn contains the number of the station that updated the SAP. Bit 7 is set if
the message was sent with a source SAP.
SrcSap is the source SAP sent in the message and is valid only if bit 7 in
SrcStn is set.
RxLen is the length of received data, in bytes. Possible values are 0 to 244.
RxData contains the received data.
