OpenBSD support has been added. Please use OpenBSD-current or OpenBSD-3.7. A null device has been added, in case you want sidetone but no keying. The 'none' sound device had been added in case you don't want a sidetone. Free entry of port names has been added, together with autodetection of ports. This should give support for more platforms.
This release adds sound card support. There are 3 extra command line options: -v for volume, -x for sound device (PC speaker or sound card), and -P for priority. Footswitch support and the new Morse character '@' have been added. Timing problems have been fixed.
