Function icom_transaction

rigs/icom/frame.c:518–556

* icom_transaction * * This function honors rigport.retry count. * * We assume that rig!=NULL, STATE(rig)!= NULL, payload!=NULL, data!=NULL, data_len!=NULL * Otherwise, you'll get a nice seg fault. You've been warned! * payload can be NULL if payload_len == 0 * subcmd can be equal to -1 (no subcmd wanted) * * return RIG_OK if transaction completed, * or a negative value otherwise indicat

 * or a negative value otherwise indicating the error.
