I must be missing something here. I performed the steps you suggested and tried again. Got the same result. Checked modprobe list and found that there are two files and one is old: -rw-r--r-- 1 root root 20319 Mar 27 15:16 /lib/modules/2.6.5-7.97-s390/kernel/drivers/s390/char/cpint_mod.ko -rw-r--r-- 1 root root 19177 Jul 2 2004 /lib/modules/2.6.5-7.97-s390/extra/cpint.ko

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. Neale -----Original Message----- 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?
