modbus_receive_confirmation - receive a confirmation request
int modbus_receive_confirmation(*modbus_t ctx, uint8_t *rsp);
The modbus_receive_confirmation() function shall receive a request via the socket of the context ctx. This function must be used for debugging purposes because the received response isn’t checked against the initial request. This function can be used to receive request not handled by the library.
The modbus_receive_confirmation() function shall store the confirmation request in rsp and return the response length if sucessful. Otherwise it shall return -1 and set errno.
