What SDSF is doing here is using the MGCRE service with the CART parameter (the "CART" is the command response token) to send the operator command to an EMCS console.
The expectation in most cases is that the code that eventually executes in whatever ASID because of the operator command looks at the CIB and sees that there is a CART present and then uses the CART=CIBXCART specification on the WTOs that writes messages containing the operator command response. This allows the EMCS that SDSF has established to wake up and get the message(s). Not all software products use CARTs on their WTOs and there may be architectural reasons why some base z/OS components do not use CARTs either. To cater for this, SDSF must establish a timer so it can give up waiting - hence the setting in the SDSF options.

I've looked at QEDIT and CIB and I don't see a way to "respond" as opposed to just "doing something."
