dosemu emulates serial ports, so no need to use a direct
access. Have you tried a $_comX settings in dosemu.conf?

You can't use a direct access to serial ports because
linux kernel already controls it.

Both problems were already fixed, upgrade your dosemu
from 1.0.2 to something more modern (unfortunately the
problem with lock files was fixed only in a devel branch,
so you will have to upgrade to a devel version I suppose).

Yes and it is not magic at all. By trying a direct access
you made a problem for yourself that wasn't existed
initially:)
