Re: How to send fax from N900?
 

I think there is fax via soundcard using fldigi in the repos, there must be a way to send the audio though the cellular modem rather than the speaker or headphone port.
If not there are several Qt packages in the Linux amateur radio family of fax apps that could be ported by someone with a working scratchbox assuming that the GSM audio codec is wide enough to permit it.
