9.1.2 Acyclic data transmission process

[9-2] Data communication via the acyclic channel

 A "Write.req" is used to transmit the data set (DB47) in the form of a parameter request

to the I/O device.

 "Write.res" confirms the receipt of the message by the I/O controller.

 The I/O controller requests the response of the I/O device with "Read.req".

 The I/O device responds with a "Read.res (-)" if processing is not yet completed.

 After parameter processing, the parameter request is completed by transmitting the

parameter response in the form of a "Read.res (+)" to the I/O controller.
