Quirks, known bugs, and other notes. ==================================== In this document I'll try to describe the behavior of the Idiom Press Rotor-EZ and RotorCard interfaces as well as the HyGain DCU-1/DCU-1X control units with Hamlib. For background information see rotorez/rotorez.txt. The Idiom Press interfaces are the most capable of the units supported by this backend and all available commands are supported by these units at this time. The HyGain control units only support a subset of the command set involving rotor positioning. This document is organized by Hamlib function calls and documents observed behavior with each call. rot_set_position * Fractional values passed for azimuth are dropped. i.e. 180.6 becomes 180 while a value greater than 359.4999 is converted to 0 for DCU1/ DCU-1X compatibility. * Allowed range for azimuth is 0 to 360. * Values passed for elevation are ignored. The protocol only supports azimuthal positioning rot_get_position * Position reading is returned in whole degrees from 0 to 359. * Not supported by DCU-1/DCU-1X. rotorez_rot_stop * Causes immediate cessation of rotor positioning. * Not supported by DCU-1/DCU-1X. rot_set_conf * Accepts one of E, e, J, j, O, o, S, and s (see rotorez/rotorez.txt) in *val. * The value in token is not used by the backend and may be safely set to TOK_BACKEND_NONE. * Not supported by DCU-1/DCU-1X.
