There are a couple of ioctls that the driver uses. The most probable is the one
that retrieves the return code. Does the zlt1 virtual machine receive the "B"?
Can you use strace to trace the syscalls of hcp?
Hang on a minute /dev/cpcmd isn't a device, there's no major/minor number. It's
not even a symbolic link to one. What happens if you modprobe -r and then rm
/dev/cpcmd. Then modprobe the module and see if the hotplug agent creates the
device node correctly.

I downloaded and installed cpint 2.5.3 on SuSE9 s/390 Linux guest. Looks
like the install went OK. But when I issue "hcp cp send zlt1 q name"
I get the response
zlt1:/home/tssrxn1 # hcp cp send zlt1 B
Ioctl: Inappropriate ioctl for device
Looks like the cpcmd device is in place.
-rw-r--r-- 1 root root 20 Mar 27 15:53 /dev/cpcmd
What am I doing wrong? Thanks
