INTRODUCING TheNet X-1J Release 4

This version is a modification to TheNet X-1J release 2 and
includes a small number of changes that I had promised.
Specifically the changes from TheNet X-1J release 2 are :

  The buffer loss problem has been fixed
  The ARP table is automatically updated from ARP requests &
  replies
  The node maintains a second heard list of L3 Netrom nodes
  that gateway through the node
  The RxDeviation & Smeter ADC channels may also be used as 
  arbitrary inputs instead
  A bug in the copying of digipeated frames in KISS mode 2
  has been corrected
  A defensive port flush function has been added
  Link list integrity checking has been extended to check
  reverse links
  A bug in handling of BBSALIAS, HOSTALIAS and DXCALIAS has
  been fixed
  The USER list shows circuit choke status for patchcord
  connections.
  BBS, HOST and DXCLUSTER are cleared properly on cold start
  The ADC* text messages may be up to 12 characters long
  The ACL checks the end user call as well as the node call
  in accepting connections.
  A default IP route entry may be made.
  Lines that start with a '#' are ignored by the switch.

The ARP table is managed by sending ARP requests and by
monitoring ARP messages received. The BBSALIAS etc commands
were compromised by the inclusion of the TexNet interface and
have been corrected.

The L3MHeard command controls a second heard list. It shows
each station that passes Net/Rom frames to the node for
gatewaying. Each entry shows the time since last gateway,
port, frames heard and the callsign of the last destination
node that the sending node was sending to.

The USER command has been enhanced to show, for each
patchcord entry, whenever one or other circuit has been
choked.

If one or other of the ADC channels used for measuring RX 
Deviation or signal strength are not required  for those 
purposes, they may be used for other purposes in a manner
similar to the other 2 ADC channels.

A menu driven windowing patch utility with context sensitive
help is included.
Utilities for printing passwords in a sysop-friendly manner
and a utility for changing the help text attributable to John
Bednar WB3ESS are also provided. Modifications for the
MFJ1278C by WB0YRQ are included in the bankswitching details.
A utility to manage the node configuration by N8PTT is
included.

     An S-meter function in the heard list
     A Voltmeter function for the other two ADC channels
     Support for the TexNet '*** LINKED to' syntax

    Level 4 retries ( min ) is now 1,
    An MTU command allows MTU settings to be changed for IP use,
    Node alias handling is optionally case sensitive,
    TALK will optionally pass 8 bit data,

    MHeard list shows whether a station is a node and / or TCP/IP station,
    A Closedown command to remotely shut the node down,
    A DXCluster command that operates like the BBS & Host commands,
    A Btext command to set the node's beacon text message,
    A Ctext command to set an optional alias connect text message,
    The ability to enable or disable any command,
    Improved command prompting with only valid commands shown,
    Routes show optionally as alias:callsign or callsign alone,
    Additional control over system reset,
    KISS as an alternative to the crosslink protocol,
    Hardware handshake controlled host mode operation,
    MODE command for configuring additional parameters,
    BBS command to auto connect to a remote BBS,
    HOST command to auto connect to another BBS or Host,
    BYE or QUIT commands to disconnect,
    STATS command to display internal statistics,
    MANAGER command for system manager access,
    AUDIT command to set system audit levels,
    Bug fixes ( e.g. info messages too long crashing the node ),
    Changes to the NODES command,
    An improved nodes broadcast algorithm for the crosslink port,
    Split port nodes broadcast intervals,
