Waveport CF user manuel Coronis Systems
RECEPTION_ERROR frame format
With this command, the local Waveport CF informs its host that a problem occurred during the exchange.
This command is forwarded between the Waveport CF and its host using the serial link, and therefore does
not require a recipient's address.
Error messages are activated only if the EXCHANGE_STATUS parameter is
set to 0x01 or 0x03.

Error frames in message mode only intervene between the transmitter and
the first repeater. Even if the other repeaters return errors, the transmitting
module does not wait for an answer and proceeds to another action.
In both cases, the procedure for sending an error frame depends on the RADIO_ACKNOWLEDGE
parameter:
