使用方法:Dim m_cs232 As New CRs232m_cs232.openPort() '打开串口Dim send() As Byte = {&H1, &H2, &H3}m_cs232.write(send) '发送Dim i as integer = m_cs232.GetReadBuffer() '得到串口输入缓冲区当前字节数Dim rev() As Byterev = m_cs232.read(3) '读取3个字节m_cs232.clsPort() '清空串口输入缓冲区m_cs
串口 实现 function TFTransForm.OpenPort:Boolean; var ret:Integer; begin OpenPort := false; ret := sio_open(GCommData.Port); if ret SIO_OK then begin MxShowError('sio_open',ret); Exit; end; if PortSet() = false then begin sio_close(GCommData.Port); Exit
LINUX+串口通讯源码 主要函数 int openport(char *Dev) //打开串口 int setport(int fd, int baud,int databits,int stopbits,int parity)//设置串口,波特率,数据位,停止位,校验 int readport(int fd,char *buf,int len,int maxwaittime)//读数据,参数为串口,BUF,长度,超时时间 int writeport(int fd,char *buf,int
