The EPICS Record Reference Manual

http://www.aps.anl.gov/epics/EpicsDocumentation/AppDevManuals/RecordRef/
Recordref-37.html#HEADING37-0

is clear that stringIn and stringOut support hardware device DTYP, for
the INP and OUT fields.

You can always look at the source code, stringinRecord.c when there are
questions like this too.

So the answer is that yes, you can write device support for those
records.
