The 2144 apparently comes from 4*536 (the latter is the default internet MTU).
The only problem I see is that in Win98 (maybe not in NT?) the window setting is
per-machine not per-adapter so I suppose I may be degrading the reliability of
my DUN connection. But I neither understand nor really care intensely.
BTW, after setting the NICs to 100 Mb/s the two boxes now chatter away happily
at ca. 4000 kb/s. Now, onward to setting up printer sharing...
Thanks for the suggestions.
