串口发送\r\n的有关问题

串口发送\r\n的问题
我需要从串口发送形如“#1P600T1000\r\n”的指令，其中P和T之间的数字是变化的
我的发送指令现在是这样写的

C/C++ code

    char sMess[] = "#1P";    DWORD sSize = sizeof(sMess);    LPDWORD ssSize = &sSize;    WriteFile(hCom,sMess,sSize,ssSize,NULL);    sSize = sizeof(sAngle);//sAngle为输入的数字转换为char*    WriteFile(hCom,sMess,sSize,ssSize,NULL);    char eMess[] = "T1000";    sSize = sizeof(eMess);    WriteFile(hCom,eMess,sSize,ssSize,NULL);    BYTE SendOrder[2] = {0x0d,0x0a};//这里把\r\n转换成16进制数出    sSize = sizeof(SendOrder);    WriteFile(hCom,SendOrder,sSize,ssSize,NULL);

C/C++ code

  char sMess[] = "#1P";    DWORD sSize = sizeof(sMess)-1;    LPDWORD ssSize = &sSize;    WriteFile(hCom,sMess,sSize,ssSize,NULL);    sSize = sizeof(sAngle)-1;//sAngle为输入的数字转换为char*    WriteFile(hCom,sMess,sSize,ssSize,NULL);    char eMess[] = "T1000";    sSize = sizeof(eMess)-1;    WriteFile(hCom,eMess,sSize,ssSize,NULL);    BYTE SendOrder[2] = {0x0d,0x0a};//这里把\r\n转换成16进制数出    sSize = sizeof(SendOrder);    WriteFile(hCom,SendOrder,sSize,ssSize,NULL);
