- This gets rid of the need to configure for parallel or serial port - The code picks up the device name from WSJT.INI for ComPort (misnamed now) which is actually a device name for either a serial port or parallel port. ptt_unix.c then uses the appropriate code to "talk" to a parallel or serial port. - audio in/audio out should work the same way on windows as it did before, however it is actually now a string name value, which can be used to open the appropriate /dev/dsp on OSS or in future, be passed to the ALSA init routines or other audio routines as needed. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/trunk@185 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
