540.0. "parity problems with Sun and telnet" by CSC32::PITT () Tue Jan 03 1995 15:28

    
    
    
    Customer has two versions of PCM running on two nodes.
    1.1 and the latest. (5.1?)
    
    He has lots of Sun systems (mostly sparc10s) connected via 90tls 
    for ue from his PCM. 
    
    When he connects to one of the Suns and either reboots it or brings
    it down to single user mode, he gets garbage out and the connection is
    "useless". This ONLY happens if he uses TELNET.
    Lat works fine. 
    
    He spoke to Sun and they told him that they do change parity when they
    go to single user mode.....(in goes to 7-even in single user mode).
    Sun also tells him that this "problem of theirs" is fixed in Solaris.
    
    Lat can handle the parity change. Telnet can't.
    Customer states that without the ability to use telnet to mamage his
    many hundreds of Suns, "PCM is useless".
    
    
    Has anyone else seen this problem? 
    
    thanks.

540.1More info please!!OPG::SIMONTue Jan 03 1995 15:5911
    Hmm,
        can you send me details of the port configs for the two terminal
    server ports that the customer uses. I.e. the LAT port which works
    and the TELNET port which does not. Also what is the exact change
    between running and console mode.I.e. is it 8bit No parity in OS
    mode and 7bit even in console mode. I shall then have a look at this.
    
    I guess the customer means V1.5 rather than V5.1
    
    Cheers Simon....

    Customer mailed me the following, stating that both his lat and telnet
    port on the 90tls are configured identically. (by the way, he also
    stated that, per Sun, parity changes from 8-none,1 to 7-even.

540.3OPG::SIMONWed Jan 04 1995 14:0415
Hi again,

	well this get curiouser as I have set up the following this morning:

PCM on ULTRIX connected to a DS90M via LAT. To act as the system I just attached
a VT200 terminal to the DS90M port. I set up the chars as per your reply and
when the VT200 is in 8bit mode all works well, but I change the terminal to 7bit
even parity and I get garbage and theis is with LAT!!!

Now I looked back through the conference so a real old note (99) and found some
info from a person who set up a SUN with PCM. I am not sure whether he used
LAT or TELNET, but he made some changes to the SUN console which helped. It's a
fairly long note with other info as well, but the SUN bit is obvious.

Cheers SImon....

    99.0 discusses some cable types to use with various systems. 
    But .1 and .2 state that it never really did work with a Sun. 
    If this is the case because of the fact that Sun changes
    character/parity when it goes to single user mode, then I will
    just let the customer know that we can't make it work and that
    the problem is with his Sun systems and Sun admitted....
    Am I on the right track here?
    
    Thanks SImon!

--------------------------------------------------------------------------------
After discussing with some SUN engineers, it seems not to be possible to
redirect the console to a ttya while continuing to work with the graphical
display ...

I will post the question in the internet news sun conference and hope I will
receive an official answer soon. Will let you know.

Marc.
540.5Two tracks!!OPG::SIMONWed Jan 04 1995 17:2715
    There are two thing here.
    
    Yes you cannot do workstations as directing the Console causes the
    OpenWindows not to start. that is a problem in SunOS just as it was a
    problem with ULTRIX. It is a brain dead way of implimenting the
    Operating system. However, that has nothing to do with the customer
    problem. If you read further down the note 99 you will see some
    commands:
    
              # eeprom ....
    
    I gather from this information that something was set in the Sun Box
    console eeprom.
    
    Cheers Simon...

    Customer has been given an UNsupported patch to the ZS driver on his
    SUN systems (by Sun). He's going to send it on to me and I'll post
    it here if it looks like it makes sense to. 
    
    He says it does eliminate this problem.
