Thank you, Bob,

The problem seems not the problem between MacOS and NetBSD/mac68k in
generall, but just between Classic II running NetBSD and another Mac.

It seems like that because my "another Mac", IIci, has also NetBSD 1.3.1
installed, and I can get to it from ClassicII running MacOS (7.1). I can
even telnet to IIci/NetBSD from ClassicII/MacOS after establishing
connection using ConfigPPP vs pppd+mgetty. In this case, pppd comes up
very happily in response to the call from ClassicII's modem port, no
matter the port on IIci is modem port or printer port. (I haven't tested
calling from ClassicII's printer port).

Being satisfied with the success above, I went further to test calling
between ClassicII/NetBSD and IIci/NetBSD. I haven't succeeded in this
yet, but I suppose there might be something wrong with my pppd settings
on the part of ClassicII. Honestly, I don't have knowledge on these
things, just trying and seeing errors :-). I'd be happy if someone would
tell me how to configure NetBSD's pppd as client for direct connection
without modem.
