 * CSDATA_SET	This call takes a pointer to a ldterm_cs_data_t data
 *		structure, and uses it to set the line discipline definition
 *		and also for a possible switch of the internal methods and
 *		data for the current locale's codeset.
 *
 *		When this message is reached, the ldterm(4M) will check
 *		the validity of the message and if the message contains
 *		a valid data, it will accumulate the data and switch
 *		the internal methods if necessary to support the requested
 *		codeset.
 *
 * CSDATA_GET	This call takes a pointer to a ldterm_cs_data_t structure
 *		and returns in it the codeset data info currently in use by
 *		the ldterm(4M) module.
