Which operating systems does KComm run under?
KComm is developed for Microsoft Windows. It has been tested using Windows XP SP2. I am unaware of any issues running it on Windows Vista, but that may be because no-one has tried to. KComm is developed using an open source cross platform development tool, Lazarus, and earlier versions were compiled and tested on Linux. As I am no longer using Linux in the ham shack I am no longer supporting KComm under Linux (although I am endeavouring to ensure that the source code still compiles under Linux) and the Linux binaries provided are untested.
