RRSUP parameter

GC27-3645-00

Use the RRSUP parameter to control the suppression of receive ready (RR) and receive not ready (RNR) frames. The line trace detail report (LDPRT) is not affected except when RRSUP=YES and scanner data is type 3.

YES
This is the default if a value is not specified or the parameter is reset. RR frames are suppressed.
NO
This value allows RR frames to be shown on the trace output report.
PAIR
This setting suppresses specific RR sequence pairs (command and response) occurring after the first pair in some output reports. This does not affect the SNA summary and detail reports (SSPRT and SDPRT) for type 1 and type 2 scanners or the normal-mode line trace data. Because of NCP processing for the line trace for duplex lines, RRSUP=PAIR does not suppress duplex line trace data.
