question about Common C++ 2 serial class

[Tim Esselens]

Hi,

I've been using your serial class for a HA (high availability) project. I've 
managed to get 2 machines to ping eachother over serial line. But there is a 
rather big problem coming up. If I flush (this->flush()) my object 
(SerialBeat: public TTYSession) the thread blocks, flushOutput() doesn't seem 
to be flushing at all.

So, the problem I'm having is quite simple, how to flush in a nonblocking kind 
of mode, so after n msecs of 'unflushability' it could start throwing errors.
I only hope the answer is as easy as the question.

If this is not possible for some reason, is there a way around this (still 
using your serial class ofcourse)? I need to detect the other side is down, 
that's really it (maybe something the serial protocol allready includes, but 
I'm new to serial lines, so I wouldn't know).

kind regards,
Tim Esselens

ps: NEWS stated sending questions to dyfet, README to bug-commoncpp, I did 
both <g>
