z/OS Communications Server
Turning 'ON" the TELNET DEBUG DETAIL function


DEBUG DETAIL

In the TCP/IP profile, add the keywords DEBUG DETAIL between the TELNETPARMS and ENDTELNETPARMS section.
Afterwards to activate function, issue command:
 
    VARY TCPIP,procname,OBEYFILE,fully.qualified.dsn

  
Note:                                                      
  When modifying Telnet parameters via an OBEYFILE command, please remember that for the Telnet Server the effect
  is not cumulative.  This is a complete replacement for ALL of the Telnet definition statements.  For this reason, and to
  also limit the OBEYFILE output messages to only your modified Telnet definitions, we encourage you to move all of
  your Telnet parameters into a separate dataset outside of the TCPIP profile.  Link the two datasets together by adding
  an INCLUDE DD statement in the TCP/IP profile.
