int HAMLIB_API rig_set_channel ( RIG rig,
const channel_t chan 

set channel data

rig The rig handle
chan The location of data to set for this channel
Sets the data associated with a channel. This channel can either be the state of a VFO specified by chan->vfo, or a memory channel specified with chan->vfo = RIG_VFO_MEM and chan->channel_num. See channel_t for more information.

The rig_set_channel is supposed to have no impact on the current VFO and memory number selected. Depending on backend and rig capabilities, the chan struct may not be set completely.

RIG_OK if the operation has been sucessful, otherwise a negative value if an error occured (in which case, cause is set appropriately).
