You might have noticed that current Wammu is not available for Windows. The reason is simple - I was not able to produce working binary in reasonable time. Python-gammu itself seems to work, but when I run Wammu, it crashes quite soon. I tried to debug it for few evenings, but I was not successful.
Therefore I again ask for somebody who would be willing to maintain Windows build. Somebody with Windows experiences will be probably able to resolve problems much faster and will help creating application that will behave good on Windows. I am not able to achieve this as I do not know Windows much and do not use it at all.
