Granting Permission to Send

When a TP in Send state receives request_to_send_received as a returned value on one of its calls to APPC/MVS, the TP can ignore the request, or grant the request by calling one of the following services:
  • Receive_and_Wait
  • Prepare_to_Receive

Any one of the above services puts the caller in Receive state and its partner in Send state. Unlike Receive_and_Wait, Prepare_to_Receive does not require a receive buffer as input.
