Once upon a long time ago, the zmodem source code was Public Domain code, and the old version of this code is still available from the comp.sources.unix (or was it comp.sources.misc?) archives.

Another possibility: "modern" (post 1988 or so) versions of kermit can be highly competitive with zmodem for file transfer throughput (at least, if you set the right options --- with sufficiently wrong options it can be glacial), and the source-available code is actively maintained.
