The first symptom is resending of packets that have already been
ack'd. After a couple of these, Win95 will abruptly jump ahead,
skipping data that has not yet been sent (or ack'd, obviously). When
the receiving end re-acks the last previously-ack'd packet, Win95
should (re)send from the last un-ack'd byte. Instead, it hangs. My
guess is that it has already free'd the unsent/unack'd packet(s).
I've seen this on Win95 dialup sessions and on sessions from Win95
users coming in from RoadRunner, the Time Warner Cable service.
I can't confirm that the DUN and winsock upgrades fixed anything, but
the users stopped complaining about problems :)
