Of course they can figure it our Brad. The developers probably know it is
needed.
BUT - if they are not hearing from LUG members that a function is needed -
the only support the developers have for persuading their management to
spend the $s is when they see votes from US.
You know what you want - it would only take you 5 minutes. I'd do it if I
knew what I was talking about!

Brad,
I had to do the same.
IBM has a tech doc on this.
It actually disables TLSV1.3, which Is the new default with the latest
CUME PTFs.
Not all our network devices support TLSV1.3, thus had to revert to
previous settings.
*TLSV1.2
*TLSV1.1
*TLSV1
TLSv1.3 could a simple change for some, but for us it will a while.

Well, my client had a call with IBM.
IBM had them change the system value QSSLPCL from *OPSYS to a list:
*TLSV1.2
*TLSV1.1
*TLSV1
And that seemed to fix their specific issue. Doesn't make sense
(well, it does). I have a feeling their trading partner was using
older version of TLS. That should have been easy to tell. Seems like
