General advice about linux serial communication API

Hello everyone,
I was wondering which display driver would be a good example on how to use a linux/unix serial line API.

The background is that following the problems I've had with the pylcd (http://lists.omnipotent.net/pipermail/lcdproc/2012-November/014074.html) and not knowing much about neither serial line development in linux nor lcdproc, I started to experiment writing a stand-alone program to interface the display, and I am running into the same (timing) issues. Now, since I took the pylcd as guidline, with termios.h and select(), this might have not a clever idea to get rid of the issues and find out whether the issues are on hardware or on driver side.

So, another good clue for me would be whether the termios.h and select() procedures are still state-of-the-art or whether there is a more modern API by now. Would maybe boost::asio be able to work on a serial line natively ? Would this be an option for a lcdproc driver ?

Many thanks in advance,
Manuel Dejonghe
