both drivewire and rzsz can do that, but drivewire is much faster. one of 
my mountable dw images is 100 megs, and while it would take a while I 
have moved several megabytes at a time to/from it and the coco3.  Bare 
in mind that rzsz is limited to (assuming a 6309 cpu) 256 byte blocks, 
and 480 cps, 240 on a 6809, until we can get the sacia.dr back into a 
bootfile with working flow controls.

But since the sc6551 is AFAIAC a broken chip, we really ought to be 
designing a better rs232 pack.  Bruce Istead had the right idea with his 
DACIA, but its a rare bird I've never seen. Could Bruce be talked into 
another run of those?
