The Gemini system supports a subset of the Meade® LX200 Command Set making it compatible to many planetarium programs using this command set. Programs featuring special Gemini drivers can make use of the additional LX200-style extensions. Gemini also supports a Native Command Set as described below. Many of these features and a hub functionality allowing several programs to access the Gemini controller simultaneously can be accessed by using an ASCOM driver .
Syntax: values in <> are (to be) replaced by actual values. Curled
