I came here to say this. I still think rz and sz should be supported everywhere. Even now, I can't tell you how many times I wish I could grab a file straight form the terminal. We lost something when we stopped using zmodem. (and for the record, yes, I do know about all the other things that aren't saving a file direct from the terminal)

On the off-chance that your use-case is "minicom to some Linux serial-console", you might be surprised to learn that minicom has rz/sz support built right into it! Assuming that your remote device has lrzsz installed, you can copy files right through your terminal, exactly like you're describing. It's certainly not the fastest transfer-rate, but it's handy in a pinch.
