A general rule of z/VM is that it will never change the type of a device, so DIAL will not change the 3270 characteristics (even though after DIAL it will appear as a local non SNA 3270)
After you DIAL to z/OS, your 3270 gets another address. You need to find the definition of that address in VTAM, a local non-SNA 3270 will it be. But, that has a logmode too, and I guess the logmode currently associated to that address defines a realy dumb 3270. In a previous life, I instructed my students of the VM/VTAM course to turn on the "query" bit in the PSERVIC: PSERVIC=X'028000000000000000000300' 2010/12/28 George Henke/NYLIC <george_he...@newyorklife.com> > How do I stop DIAL from turning off the Extended Data Stream (EDS) terminal > attribute? > > I have NSX32702 Logmode (NSX means Non-SNA EDS) before dialing my z/OS > guest. > > The ISPF ENVIRON TERMSTAT Query on native z/OS shows: > > ISPF TERMINAL CHARACTERISTICS > *14 BIT ADDRESSING = ON* > 16 BIT ADDRESSING = OFF > *EXTENDED COLOR = ON * > *EXTENDED HIGHLITING = ON * > > After dialing the z/OS guest with the same Logmode the z/OS ISPF ENVIRON > TERMSTAT Query shows: > > ISPF TERMINAL CHARACTERISTICS > *14 BIT ADDRESSING = OFF * > 16 BIT ADDRESSING = OFF > *EXTENDED COLOR = OFF * > *EXTENDED HIGHLITING = OFF * > DBCS = OFF > > > DBCS = OFF > -- Kris Buelens, IBM Belgium, VM customer support
