What: MXSER
When: December 2007
Why: Old mxser driver is obsoleted by the mxser_new. Give it some time yet
and remove it.

Say Y here if you have a Moxa SmartIO multiport serial card.
This driver can also be built as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called mxser. If you want to do that, say M
