Laplink between System 5/6ish and macOS (X)?

[rieSha.]

Hi,

I got hold of the old Laplink Mac software of the System 5/6ish era, which was together with some 5.25" disks for MS-DOS, to transfer stuff from Macs to PCs without networking (box images)

I’d love to use the Sys5 software part, but interface to something UNIXish/for macOS. Does anyone know of a re-implementation of the Laplink protocol?

Sure, I could use the nullmodem cable together with ZTerm/Terminal 2.2/BlackKnight and ZMODEM or the like, but the Sys5 Laplink software side is a bit nicer …
