NAME

       AF_ROSE - Rose amateur packet radio protocol family

DESCRIPTION

       Rose  is  a protocol used extensively by radio amateurs. The Linux Rose protocol family permits access to
       these protocols via the standard networking socket metaphor.

       The Rose protocol layer only supports connected mode.

       The only mode of operation is connected mode which is the mode used for a socket of  type  SOCK_SEQPACKET
       (stream  sockets are not available in Rose).  This requires that the user ensures output data is suitably
       packetised, and that input data is read a packet at a time into a buffer of suitable size.

       Rose addresses consist of 10 digits. These are encoded into a sockaddr_rose structure which  is  provided
       to the relevant system calls.

       Rose  has  some  unusual  properties. Notably in a multi-user system an AX.25 address is often associated
       with a user, and some users may not have such an association. a set of ioctl calls are provided to manage
       an association table.

       Rose  supports  the  following  socket options for SOL_ROSE. ROSE_T1 is the T11/T21 timer in 1/10ths of a
       second, ROSE_T2 is the T12/T22 timer in 1/10ths of a second. ROSE_T3, is the T13/T23 timer in 1/10ths  of
       a  second.   It  is  possible for an application to request that the Rose layer return the Rose header as
       well as the application data, this is done via the ROSE_HDRINCL socket option.
