Description of Arguments
Command only.
Clears the Compression Statistics
Example: CCS=
Command only.
Clears the Decompression Statistics
Example: CDS=
Query Only.
Queries all compression statistics in the form A.AE+AA:B.BE+BB:CC:DD, where:
A.AE+AA = The total number of bytes into the compressor (XXE+XX)
B.BE+BB = The total number of bytes out of the compressor (XXE+XX)
CC = The compression efficiency (00-99%)
DD = The last 10 second compression efficiency (00-99%)
Each parameter is separated by a colon.
If the option card is not present, all numeric fields display "X"
Example: CSA=A.AE+AA:B.BE+BB:CC:DD
Query Only.
Queries all decompression statistics in the form A.AE+AA:B.BE+BB:CC:DD, where:
A.AE+AA = The total number of bytes into the decompressor (XXE+XX)
B.BE+BB = The total number of bytes out of the decompressor (XXE+XX)
CC = The decompression efficiency (00-99%)
DD = The last 10 second decompression efficiency (00-99%)
Each parameter is separated by a colon.
If the option card is not present, all numeric fields display "X"
Example: DSA=A.AE+AA:B.BE+BB:CC:DD
Command or Query.
Used to enable/disable payload compression and decompression in the form x,
where:
0=Disable Decompression and Compression
1=Disable Decompression, Enable Compression
2=Enable Decompression, Disable Compression
3=Enable Decompression and Compression
Example: EPC=1 (decompression off and compression on)
