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 net-
working 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 sock-
addr_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 sec-
ond. 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.
