"Priority Message/Command" is an SCLP architecture term. The SCLP architecture is not externally published, as far as I know, so I can't say a lot about it. Although, I am told that some uses of it are visible in Linux source code, if you like to read C source (I don't). http://lxr.free-electrons.com/source/drivers/s390/char/ Look for file names that start with SCLP. z/OS uses priority messages for disabled console communication, and for disabled console WTORs, it enables only for priority responses. So if z/OS running under VM uses SCLP for a disabled console WTOR, and you try to reply to it with VMSG, it will be ignored. You have to use PVMSG to respond to z/OS disabled console WTORs.
