/* 打开串口*/

}

/* 配置串口*/

}

/* 串口接收数据 */

width＝sfd +1; //这里应该如何运用？

/* 任务阻塞等待读串口准备完毕 */

/*line 85*/ if(select(width，&fds_data，NULL，NULL，NULL)==ERROR)

return(ERROR);

read(sfd, accept_buf,sizeof(accept_buf)); //从串口读字符

printf("accept message is : %s \n\n", accept_buf); //输出接收到的信息
}

}

/* 串口发送数据 */

int send_com2(void) //向串口1发送数据函数

{
char *send_buf =" Data had accept!"; //待发送数据

//任务阻塞等待写串口准备完毕

if(select(width，NULL，&data_fds，NULL,NULL)==ERROR)

return(ERROR) ;

/*line 109*/ if(FD_ISSET(sfd，&data_fds)) //检查串口准备好就向串口写数据

write(sfd，send_buf，sizeof(send_buf)) ;

}

/*关闭串口*/

/*void close()
{
close(sfd)；
}
*/
错误提示如下，请帮忙看一下，谢谢！
