If it is a C0D-01 abend, it means that z/OS was presented with an I/O interrupt with what we consider to be invalid status in the IRB. I would need to see the contents of the IRB and review the I/O architecture to rule on whether or not the status is architecturally valid.

Based on some of the other replies, it probably is my emulator. But I did discover an easy work-around: From the VM userid, I go into CP READ and issue a 'RESET vaddr' of the console address. This does allow z/os to recognize the device as a mod-5, so all is good now. The RESET does have the side effect of causing an abend in IOS: DUMP00 TITLE=COMPON=IOS,COMPID=SC1C3,ISSUER=IOSVIRBA,IRBAFRR Thank you.
