If the problem is something in the LAT software, a possible solution
is to use our SCSI serial/parallel servers.  From what I have been
told of LATs (we don't have any to compare against), they have higher
performance.  And they certainly cost a lot less than LATs and relieve
a lot of ethernet load.  Plus you get a Centronics parallel port for
each 8 serial ports.
