I reviewed docs for amodem, and it looks like I can send files and possibly other things with this.
I should only need to prep my computer as per the doc and set VOX correctly. Does anyone have experience with this software, or a recommendation for something better (linux/bsd)?
amodem {send,recv} --calibrate
. Only tried peer-to-peer, not over repeaters, which is likely frowned upon for this kind of tomfoolery anyway. $\endgroup$
