I am sorry that you are having problems with one of our cards, below
is a summary of my thoughts on the matter. If you have any further
information/questions  please feel free to email me.  General support
questions should be addressed to support@specialix.com or
support@specialix.co.uk (both go to the same list).

If the port is already open then the setting should remain static,
we use a printer script that does the following:

sleep 20 >/dev/ttywhatever
stty settings for port
 .. rest of script to output data.

However if you are doing this and having problems then it would appear
to be a bug.  We will investigate this.   We have an outstanding bug report
for the differing initial setting and that is being fixed at the moment.
I will ensure that your bug is also investigated before 3.12 hits QC.
