ACE关于串口通信的反应器
请问我使用ACE编写了一个串口通信程序，使用了反应器，但是问题是有数据发过来input_handle方法始终不会被调用是怎么回事？代码如下：
#include "ace/Connector.h"
#include "ace/DEV_Addr.h"
#include "ace/DEV_Connector.h"
#include "ace/TTY_IO.h"
#include "ace/Reactor.h"
#include "ace/Svc_Handler.h"
#include <iostream>
typedef ACE_Connector<MyHandler,ACE_DEV_CONNECTOR> MyConnector;
class MyHandler:public ACE_Svc_Handler<ACE_DEV_STREAM,ACE_NULL_SYNCH>
{
private:
//ACE_TTY_IO recv;
char sizeBuffer;
public:
MyHandler()
{
ACE_TTY_IO::Serial_Params S_Params;
S_Params.baudrate = 9600;
S_Params.xonlim = 0;
S_Params.xofflim = 0;
S_Params.readmincharacters = 0;
S_Params.readtimeoutmsec = 1000;
S_Params.parityenb = true;
S_Params.paritymode = "EVEN";
S_Params.ctsenb = false;
S_Params.rtsenb = false;
S_Params.xinenb = false;
S_Params.xoutenb = false;
S_Params.modem = false;
S_Params.rcvenb = true;
S_Params.dsrenb = false;
S_Params.dtrdisable = false;
S_Params.databits = 8;
S_Params.stopbits = 1;
//S_Params.parityenb = true;//奇偶校验
this->peer().control(ACE_TTY_IO::SETPARAMS,&S_Params);
}
int open(void*)
{
ACE_DEBUG((LM_ERROR,"COM OPEN"));
this->peer().send("hello",sizeof("hello"));
ACE_Reactor::instance()->register_handler(this,ACE_Event_Handler::READ_MASK);
return 0;
}
int handle_input(ACE_HANDLE)
{
if(this->peer().recv(sizeBuffer,sizeof(sizeBuffer)) < 0)
ACE_DEBUG ((LM_ERROR,ACE_TEXT("%p\n")));
else
ACE_DEBUG ((LM_ERROR,ACE_TEXT("Receive:%s\n"),sizeBuffer));
return 0;
}
};
int main(int argc,char* argv[])
{
MyConnector conn;
MyHandler *eh = new MyHandler;
ACE_DEV_Addr comaddr("COM1");
if(conn.connect(eh,comaddr) < 0)
ACE_ERROR_RETURN ((LM_ERROR,
ACE_TEXT ("Connect Error!")),
1);
ACE_Reactor::instance()->run_reactor_event_loop();
return 0;
}
ACE_Reactor::instance()->register_handler(this,ACE_Event_Handler::READ_MASK);
我没在串口上面用过这个系统，但这句决定了反应器的行为，请检索和尝试变更掩码参数试试看。 winston 发表于 2012-10-21 19:14 static/image/common/back.gif
ACE_Reactor::instance()->register_handler(this,ACE_Event_Handler::READ_MASK);
我没在串口上面用过这个 ...
我试了其他掩码也不行，不知道串口上是怎么使用反应器接受数据的，有高手解决下吗
moving this->peer().control(ACE_TTY_IO::SETPARAMS,&S_Params); after register_handler;
should fix the issue
