Is the protocol used by the DOS Laplink software publicly documented?
I seem to remember there were Linux tools that could use it.
I cannot find anything useful on their website.
- 1Are you sure it is the laplink protocol or was it just the laplink cable?cup– cup2021-06-27 15:20:36 +00:00Commented Jun 27, 2021 at 15:20

- 3This suggests that different versions of Laplink used different protocols, and the timing seems to depend on system speed. One way to find out would be to reverse-engineer the Laplink binary.dirkt– dirkt2021-06-27 19:54:12 +00:00Commented Jun 27, 2021 at 19:54

As far as I’m aware, it isn’t.
I don’t remember any Linux software capable of connecting to LapLink; the latter was commonly mentioned because the cable provided with it could be used with a variety of tools. DOS-to-Linux connections with null-modem cables usually involved PLIP, SLIP or PPPD rather than LapLink-style tools.

- @RuiFRibeiro PLIP does the same, but unfortunately not in the same way.tofro– tofro2021-07-24 12:46:15 +00:00Commented Jul 24, 2021 at 12:46
