Yeong,
    I can't speak for the ZyXeL driver, but I can speak for DFax.  This very  
thing you mention (locking) is one of the things we've had to address, and one  
of the things which have put us behind our originally targetted release date  
for DFax - THE Fax/Data driver for the Supra.

    Not only, does DFax not block other processes after sending a fax, it does  
not block ANY access to the port while watching for incoming calls.  It would  
even be possible with the correct hardware to share the port with non-modem  
hardware such as a tablet or digitzer, with DFax active!

    As for suggestions -- probably the easiest method of regaining access to  
your port ( for the lay user ) is to open an application already set to crack  
such locks, like the Microphone II terminal program.  Open the connecton to the  
port, and OK the over-ride locks prompt.

Bruce
