The TCP timer is fixed at 3.0 seconds in pre-7.0 HP-UX.  This will change to	the adaptive mode in the 7.0 release. On the RS20, if you have the 3Com Lan
card then the problem here is due to the 1-packet buffer limit on the card.
If back-to-back packets arrive and the cpu is busy, the second gets dropped,and
3 seconds later the timer pops. New card in the works for thinlan & a new card
for Starlan 10  exists that has more buffering.
