device-independent asynchronous access to fixed size blocks onCMS format
ted virtualDASD I/O devices.
IUCVInter-User Communication Vehicle (IUCV) extensions provide: SEND and REPLY extensions
An extended mask capability for control interrupts
An expanded trace capability to record allIUCV operations
A macro option to initialize the parameter listSupport for the DASD block I/O system service.
The IBM3088 Multisystem Communications Unit
The IBM3088 Multisystem Communications Unit interconnects multiple sys
tems using block multiplexer channels. The3088 uses an unshared sub channel
for each unique address and is fully compatible with existing
channel-to-channel adapter protocol.Summary of Changes iii
