FACILITATING TRANSPORT MODE INPUT/OUTPUT OPERATIONS BETWEEN CHANNEL SUBSYSTEM AND INPUT/OUTPUT DEVICES Russian patent published in 2014 - IPC G06F13/42 

FIELD: radio engineering, communication.

SUBSTANCE: apparatus comprises a channel subsystem, a host system, a control device, the channel subsystem being configured to transmit, to the control device, a process login request which indicates whether the channel subsystem supports two-way data transmission; receiving, from the control device, a response to the process login request indicating whether the control device supports two-way data transmission; collecting a plurality of instructions in at least one of which input data transmission is indicated and in at least one of which output data transmission is indicated; transmitting, to the control device, at least one output information message containing output data to be transmitted to the control device, wherein the output information message is associated with at least one of the plurality of instructions in which output data transmission is indicated; and receiving, from the control device, at least one input message containing input data to be stored in the main storage device of the host computer system.

EFFECT: easier processing by supporting two-way operations.
