nrports - NET/ROM port configuration file.
Nrports is an ASCII file that contains information about each of the
NET/ROM ports that are to be used. When dealing with an NET/ROM utility
such as call, it takes an optional argument that is the port name. This
port name is a reference to the line within nrports, which has the same
name. The information on each line contains enough information to bind
the command to a particular NET/ROM interface, this binding is done by
matching the callsign on the line in nrports with the callsign of the
port set by ifconfig.
The nrports 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 callsign alias paclen description
The field descriptions are:
name this is the unique NET/ROM port identifier.
callsign the callsign of the NET/ROM interface to bind to.
alias this is the alias of the NET/ROM port.
paclen is the default packet size for this interface.
description a free format description of this interface, this
field extends to the end of the line. It may
call(1), netrom(4), ifconfig(8), nrparms(8).
