Long ago I sent a patch for uploading downloading using this escape sequence, using zmodem like how an old windows SSH client (I forget the name) used to allow uploading/downloading files. You log in, type "rz<enter>", and then use escape sequence to upload a file. (similar for downloading) The patch was rejected. Shame. It's very useful when hopping 6 steps to upload a file.[1] I can't find the patch now, but I'm considering rewriting it as a an `expect` script. My `expect` scripts tend to have trouble with SIGWINCH propagation though, so not optimal. Also you have to remember to wrap with the `expect` script at (and preferably only at) the one "jump" you want to send from/to with the final destination. [1] No, nothing illegal. Just that some networks mandate SSH jumpgates, and sometimes multi-level.
