function maps the direct access hardware memory to be able to
communicate with a VULOM/TRIDI running the TRLO II firmware.
vmvk holds the address of the module as given by the
two HEX switches. unmapinfo is a pointer to a pointer
to optionally store unmap information. It may be NULL.
The returned pointer is used by all other read and control functions.
Can also be used directly with the defintions in
Note that this function calls
function checks that the module/firmware accessible at the

This can be used if the memory mapping has been provided elsewhere,
