PI14661: TELNET CLIENT RUNNING A SCRIPT HANGS AFTER RECEIVING DEFAULT MSG10 - FIN REVERSAL OF PM85497

Obtain the fix for this APAR.

APAR status

• Closed as unreproducible in next release.

Error description

• Client running a logon script receives MSG10 and hangs.  Telnet
  solicitor screen increased in size causing clients which counted
  bytes received from Telnet instead of parsing the 3270 data to
  fail. The solicitor screen was modified to include space for
  password phrases. This APAR is a logical route of FIN APAR
  PM85497.
  

Local fix

• Code a DEFAULTAPPL in the Telnet Server profile

Problem conclusion

• An application which simply counted the number of bytes
  received from Telnet instead of parsing the 3270 data
  will see different behavior in v2r1 when the
  solicitor screen is received.  The solicitor screen was
  modified to include space for password phrases.

Temporary fix

Comments

• A new keyword is defined to provide support for only a password
  (8 bytes or less) and is sent in the same format as prior to
  z/OS v1r13.
  The new keyword is DISABLEPASSWORDPHRASE. It can be specified
  on TelnetGlobals, TelnetParms, and ParmsGroup.
  
  EZBTDPRM, EZBTDPRU, EZBTMPRB, EZBTMPRP, EZBTMPRT,
  EZBZPRMG, EZBZSOLC, EZBZVREQ, EZASMF77, EZASMF
  are all updated to allow the specification and propagation of
  the new keyword.
  
  EZBTPSOW is updated to fix PASSPHRASE support and add
  DISABLEPASSWORDPHRASE functionaility.
  
  EZBTMQPR is updated to allow the display of the presence of the
  new keyword in PROFILE, CONN, and CLID displays.
  
  EZBDGPRG is updated to allow TCPIPCS PROFILE to display the new
  keyword.
