ABSTRACT
========

This document contains details of all of the commands to be found in  
the following TCP/IP Network Operating System ("NOS") packages:

            KA9Q/PA0GRI: version 900819
            KA9Q/G1EMM:  version KH113014


CHANGES FROM PREVIOUS VERSION
=============================

Minor corrections to the "route" command syntax.

Familiarity with the basic functions of the "NOS" packages is assumed.   
This document is intended only as a quick reference to the TCP/IP 
command set, and does not describe how individual commands work.  


RATIONALISATION OF PARAMETER DESCRIPTIONS
=========================================

Because the "NOS" packages contain software modules originating from  
several different sources, the documentation which describes them  
inevitably contains a number of inconsistencies.  For example, the  
words "label" and "interface" apparently describe different objects,  
whereas in actuality they are the same thing.  On the other hand, the  
meaning of the word "address" used in many commands differs from  
command to command.

In this document an attempt has been made to rationalise the meaning  
of these parameters, to produce a consistent command set within and  
across the two "NOS" packages.  

The principal parameters which have caused confusion in the past are  
to do with names, addresses and interfaces.  These are now defined 
as follows:

      <callsign>    an AX.25 MYCALL callsign (e.g. "G3NRW-1")
      <hostname>    a computer name (e.g. "g3nrw" or "g3nrw.ampr.org")
      <ipaddress>   an Internet address (e.g. "44.131.5.2")
      <host>        <hostname> or <ipaddress>
      <username>    a user at a computer (e.g. "ian")
      <interface>   a device interface name (e.g. "pk0" or "ax0")
      <ioaddress>   a device I/O base address (e.g. "0x3f8")
      <vector>      an IRQ level (e.g. "4")

(Note that the word "hostid" is not used in this document, to avoid 
confusion with the Unix command of the same name).


TCP/IP "NOS" COMMAND SET REFERENCE
==================================

The rest of this document specifies the complete "NOS" command set 
for the KA9Q/PA0GRI and KA9Q/G1EMM packages.

The extreme left-hand column of each line is coded as follows:

i |     signifies a command in the KA9Q/PA0GRI version of "NOS" 
 m|     signifies a command in the KA9Q/G1EMM version of "NOS"

The extreme right-hand column shows the default values of command 
parameters.
