Hi Gilles,

Thanks a lot. Will give it a try. I have tried  .rx_timeout =
RTSER_TIMEOUT_NONE before, but then I was not able to read any data. I am
assuming the data expired before I had read it. This was on a different
config however, so I will try it again.

Please excuse my lack of knowledge but I am not following you on:
-  ... and apply the commit 3a23967f3cc8d6881d8e3280130bbc431195aa31
-     from head.

Thanks again and kind regards,
Dehann
