I vaguely remember someone discussing something like this on the
kde-devel or kde-core-devel lists a while back (months). It may
have been Kalle, but I'm not sure. I'd suggest that one of those
places (and perhaps the qt-interest list) would be your best bet
for finding code like this.

Hmm, you should definitely discuss this on kde-devel. This would
be useful tool for everyone needing serial port access so it might
make sense to put it in a library when you've got something working.
