We had the same problem with the eports boards on our 3B2/500.  We
found that we were running release 1.1 of the eports software 
(which was loaded off the tape), but that we had release 1.2 on
installable diskettes.  When we removed 1.1 and installed 1.2, the
problems pretty much went away.  (We were able to use the 1.2 disks
to remove the 1.1 sotware.) We still occasionally experience a hung 
port, probably because we running too many ports on individual boards 
at 9600 baud.  We spread the load out across the boards; this seems 
to help, too.  

There are some fairly severe limits as to the number and speed for 
the ports on the ports and eports boards.  You should be able to 
find that in the eports docs.
