Rsports is an ASCII file that contains information about each of the Rose ports that are to be used. When dealing with a Rose utility such as call, it takes an optional argument that is the port name. This port name is a reference to the line within rsports, which has the same name. The information on each line contains enough information to bind the command to a particular Rose interface, this binding is done by matching the address on the line in rsports with the address of the port set by ifconfig or rsattach.
The rsports file may contain comments that begin with a # in the first column, or a port description in the following format, each field being delimited by white space:
name address description
The field descriptions are:
this is the unique Rose port identifier.
the address of the Rose interface to bind to.
a free format description of this interface, this field extends to the end of the line. It may contain spaces.
call(1), rose(4), ifconfig(8), rsparms(8).
ax25d.conf(5), call(1), rose(4), rsattach(8), rsparms(8).
