The length of Radio Text strings depe used to transmit it, either 32 (2A block) or 64 (2B block). However, it is also possible to find receivers which can scroll strings sized as 32 x N or 64 x N characters. So, this control must be configured with steps of 32 or 64 characters. The result is it must always contain a string with size multiple of 32 or 64. + + + V4L2_CID_RDS_TX_MONO_STEREO  + boolean + + Sets the Mono/Stereo bit of the Decoder Identification code.
