Command or Query.
Enable or Disable Payload Compression and Decompression in the form x, where:
0=Disable Decompression, Disable Compression
1=Disable Decompression, Enable Compression
2=Enable Decompression, Disable Compression
3=Enable Decompression, Enable Compression
EXAMPLE: <0/EPC=1 (selects decompression off and compression on)

EPC=x
Compression Stats
All
N/A CSA? 21 bytes Query only.
Returns all compression statistics, each separated by a colon, in the form x.xE+xx:x.xE+xx:xx:xx, where:
x.xE+xx=The total number of bytes into the compressor
x.xE+xx=The total number of bytes out of the compressor
xx=value from 00 to 99 (The percent savings or compression efficiency)
xx=value from 00 to 99 (The last 10 seconds percent savings or compression efficiency)
EXAMPLE: <0/CSA?
RESPONSE EXAMPLE 1: >0000/CSA=2.0E+03:1.0E+03:50:50
RESPONSE EXAMPLE 2: >0000/CSA=X.XE+XX:X.XE+XX:XX:XX (If the Compression Option Card is not present, then
all numeric fields display "X")
N/A CSA=
x.xE+xx:x.xE+xx
:xx:xx
DeComp Stats All N/A DSA? 21 bytes Query only.
Returns all decompression statistics, each separated by a colon, in the form x.xE+xx:x.xE+xx:xx:xx, where:
x.xE+xx=The total number of bytes into the decompressor
x.xE+xx=The total number of bytes out of the decompressor
xx=value from 00 to 99 The percent savings or decompression efficiency
xx=value from 00 to 99 The last 10 second percent savings or decompression efficiency
EXAMPLE: <0/ESA?
RESPONSE EXAMPLE 1: <0/DSA=2.0E+03:1.0E+03:50:50
RESPONSE EXAMPLE 2: <0/DSA=X.XE+XX:X.XE+XX:XX:XX (if the Decompression Option Card is not present, then
all numeric fields display "X")
N/A DSA=x.xE+xx:x.
