Public bug reported:
Trying to receive the following r232 sequence (9600N81) on ttyS0 with Serial
port terminal
d1 fa fb 00 0a ff. This sequence is sent by another PC with a null modem cable
which works in XP. In ubuntu 9.04 I receive distorted data, mostly unpredictable
following 00.
The same happens to a real device which is connected to ubuntu using an normal
rs232 wire.
Sending data from the Ubuntu machine to an XP machine works OK.
Ubunto 2 Ubuntu I get the same faulty data.
Tested this with several machines in our lab and I always get the same
behaviour. Also this is an issue with 8.10 I was able to test on.
Please help us out.
