Are you still dependent on the Network Control Program (NCP) ?

Do you still have VTAM SNA (Systems Network Architecture) solutions that require NCP ? If so, I assume you don't use the old communication controllers (3745, 3746 or other) anymore, right ? Instead you migrated to the IBM Communication Controller for Linux on System z (CCL) that works together with the OSA Express adapter - CHPID type OSN. Are you using that approach for NCP ?
It would be great, if I could get your feedback. Please sent your feedback to my email address: firstname.lastname@example.org.
If you want to understand, what I am talking about - here the link to more information.
The description is z/OS related and a bit outdated, but the basic information is also valid for z/VSE. CHPID type OSN is available on the OSA Express3, OSA Express4S and OSA Express5S cards too.
Have a good weekend.
