The Linux +NET/ROM protocol family permits access to these protocols via +the standard networking +.B socket +metaphor. +.LP +The NET/ROM protocol layer only supports connected mode. IP traffic may be +stacked on top of NET/ROM frames using a non-standard extension to the +NET/ROM protocol. +.LP +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 NET/ROM). +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. +.LP +NET/ROM addresses consist of 6 ascii characters and a number called the +SSID. These are encoded into a sockaddr_ax25 structure which is provided to +the relevant system calls. +.LP +NET/ROM 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. +.LP +NET/ROM supports the following socket options for SOL_NETROM. NETROM_T1 is +the T1 timer in 1/10ths of a second, NETROM_T2 is the T2 timer in 1/10ths of +a second. NETROM_N2, the retry counter is also configurable. There is no 'infinite +retry' option supported however. It is possible for an application +to request that the NET/ROM layer return the NET/ROM header as well as the +application data, this is done via the NETROM_HDRINCL socket option. +.SH "SEE ALSO" +.BR call (1), +.BR socket (2), +.BR setsockopt(2), +.BR getsockopt(2), +.BR nrbroadcast (5), +.BR nrports (5), +.BR netromd (8), +.BR noderest (8), +.BR nodesave (8), +.BR nrctl (8), +.BR nrparms (8). +.LP +.SH AUTHOR +Jonathan Naylor G4KLX -- cgit v1.2.3
