The complexity of this procedure depends a lot on what kind of software and equipment you already have.
It's true you can use a nullmodem cable, but that only works if you have some kind of terminal software on your amiga already. If you don't, how are you going to transfer it?
Sure, you can save files to a pc-formatted 720k disk and mount it on the amiga, if you have a never version of workbench or some kind of crossdos driver that allows you to mount pc-formatted DD disks. If you don't, you're more or less stuck in a dead end.
So, if you can mount pc-formatted disks (720k) anything is possible really. If you have a harddrive it gets even easier. If not, then it becomes a bit more complicated but not impossible.
It's easier to tell you how to go about this if you let us know what you have. What version of AOS, do you have a harddrive, an extra diskdrive and so on.
