The following example is how to use the SF_SET_LINKS function. It is presumed that a call to
F_INQUIRE---.ALL has been made, and that the device at address #3, is a tablet. The tablet is
going to be mapped to the V_LHPMOUSE driver. The BX register already has the offset into the
buffer of tablet mappings.
