"quit" commad can't quit the console application

[Brhett]

The "read" method is blocking in the thread "ZToolPacketParser". Thus, "parserThread.join()" might be blocked during closing of "ZToolPacketParser".

Tested on the current head version eaf7129.

Repeats still on Macbook Pro.

The root cause should be the port implementation of libjSSC-2.8_[x86].so that the select() is blocked even if the handle was closed. A possible trick to fix this issue is adding a timeout to select() and check the return value of it. See pseudo-code below.

int ret = select(portHandle +１, &read_fd_set, NULL, NULL, &internal_timeout);
if (ret == -1)
{
    throwSerialPortException(...);
    return NULL;
}
else if (!FD_ISSET(portHandle, &read_fd_set))
{
    continue;
}
