Thanks a lot! I keep being impressed by how quickly you respond. For
time frame: We need to have a working system this month :) Serial
communication i critical core functionality, and must work reliably.
I'm at home now and for some reason my laptop has no serial port, so
Linux reports IOError on any operation on /dev/ttyS0, but I will enter
the bug report into JIRA from memory. Spent all of yesterday and
Thursday on this :) Will retry on monday.
