The OS/2 Museum claims at [1] that the network

3.0. I'd expect INTERLNK/INTERSVR to need redirector support, and if
that assumption is correct, those wouldn't work on any pre-3.0
versions of Microsoft's DOS (whether MS-DOS or PC-DOS), and support
may be spotty on versions earlier than the one where they were
introduced depending on which exact features are used.
A prototype was introduced in 3.0; it wasn't exactly usable until 3.1
iirc.
Also, a cursory glance at a MS-DOS 3.1 user's
manual and user's
reference that I have lying around does not list INTERLNK/INTERSRV in
the command reference, so those would presumably have come later than
that. Wikipedia appears to confirm this at [2] by claiming they were
introduced in PC-DOS 5.02 / MS-DOS 6.0; the cited source at [3], [4]
simply says "6.0 and later" without specifying a variant.
I can confirm the presence of Interlnk in PC DOS 5.02 as well as MS-DOS
6.00 (and this is why I specifically mentioned those versions). I've done
a lot of research on MS-DOS/PC DOS history. ;p
Interlnk does have a way, as I mentioned, to copy itself over a serial
cable. I suppose it probably relies on CTTY and DEBUG or something.
