Description: TKSA is a low-level serial routine used to send a secondary address (SA) to a device commanded to TALK (see TALK Kernal call). An SA is usually used to provide setup information to a device before the actual data I/O operation begins. (Most applications should use the higher-level I/O routines; see OPEN and CHKIN).
