在C++中打开一个数字高于9的COM端口

HANDLE comHandle = CreateFile(L"COM1:", GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL);

int com_port = 12345;
int fd = open("/dev/ttyUSB0", O_RDWR | O_NOCTTY);
if (fd < 0) {
    // error handling
}

DWORD bytesRead;
BYTE buffer[1024];
COMSTAT comStat;
HANDLE comPort = CreateFile(L"COM1:", GENERIC_READ, FILE_ATTRIBUTE_NORMAL, NULL, OPEN_EXISTING, 0, NULL);
if (comPort != INVALID\_HANDLE\_VALUE) {
    while (ReadFile(comPort, buffer, sizeof(buffer), &bytesRead, NULL)) {
        // process data
    }
    CloseHandle(comPort);
}

int bytesRead = read(fd, buffer, sizeof(buffer));
if (bytesRead > 0) {
    // process data
}
