ABSTRACT:
A SYStem COMmunication interface (SYSCOM) unit provides uniform communication between hardware and software units of a computer system. The computer units include Central Processing Units (CPU's), Input/Output Processors (IOP's), Service Processor (SVP), and Control State Software (CSSW) which runs on the CPU's operating in Control State. The SYSCOM communication interface includes signalling hardware, control blocks in storage, and a uniform communication method used for communication between the computer units. The communication method sends messages between an originating unit (ORG.U) and one or more destination unit(s) [DES.U(s)].
