Communications Standard Return Values
Communications standard return values are sent to a JANUS application to
indicate the result of a communications function call, such as
im_rx_check_status.
When you customize the INI file for the Simulator TSR, you can set these
four parameters to a communications return value:
• rx_check_status_return
• cancel_rx_buff_return
• protocol_ext_status_return
• cancel_tx_buff_return
