# nrports(5)

NET/ROM port configuration file.

## NAME

nrports - NET/ROM port configuration file.

## DESCRIPTION

**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 contain spaces.
