We have had similar trouble. The clash seems to be the serial
port configuration and its speed. It allows the communication
to run out of sync. You might get away using the internal com
ports (ask Terry at Applied cytometry systems:

try to swap ports 2 and 4 or try to quiz our computer guru's
to find out what they did with our system or buy the upgrade
from Coulter which might be the cheaper solution in the long
run. The trouble is indeed computer version specific,
depending what serial chip / timing is installed.

Good luck

Dear Coulter Elite Users: Our recent attempt of replacing the 386 PC
on the EPICS ELITE finally drowned in futility. We had a 66 mHz 486
Zeos PC, with a 600 MB HD. It looked a good match. After trials and
tribs with mixed up RS 232 port addressing, we thought finally we had
it together. Only to realize that the COULTER LISTER board will not
transmit to the PC logic in any shape or form, even though it seems
collecting data from the cytometer. Upon suggestions from Coulter
people (who by the way exhibited exemplary helpfulness), we swapped bus
locations, cleansed contact points until the bovines came home, nothing
doing. So in disgust we gave up and reconfigured the old 386 sloth
back to its original snail paced state. Caveat igitur: The COULTER
lister board will most likely not work with 486 backplanes. How true is
this for different brand PCs? ... is a good question. Pete Bercz USEPA
