It is likely that supposedly identical models of those modems with slightly different
firmware revisions
would not show the same problems. I know of at least 150 different firmwares on a
single model of
"sportster" modems with nothing to tell them apart for the consumer.
What you probably want is irqtune to move the serial ports up in the priority stack
for interrupt
handling. If you search the archives with the keywords "Civileme" and "www.best" you
will likely find
the URL explaining the principle and providing the download.
