And I can confirm that it does work on DOS 3.30. I wasn't aware that
it had that sort of history, but such are things. I've used it to send
things from a small portable to a laptop the laptop ran DOS 6.22, and
the portable was running 3.30
Mary Anne you own an AT&T PC 6300? Wow, I got my start along the
regular desktop market with one. And their 80286 version as well.

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
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  by claiming they were
introduced in PC-DOS 5.02 / MS-DOS 6.0; the cited source at , 
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.
