@chapter Changes to Operating Procedures
@label[chapter-operating]

This chapter details changes to functions and variables
that are part of the networking software.
The functions include general system management and operating procedures.

This chapter contains only a summary of changes;
complete documentation on operating procedures is in
Chapter @ref[chapter-doc-operating], below.

Changes to specific TCP/IP protocols are discussed in
Chapter @ref[chapter-tcp-app], @b[@nameref(chapter-tcp-app)].

@section Name Changes and Deletions

@ref[figure-name-changes], shows the most significant
name changes and deletions
to networking functions and variables.

@caption Summary of Changes to Functions and Variables
@end(fullpagefigure)

@section Functions

Many of the network configuration and management functions
have been replaced, as described below.

@itemize @bullet

@item Resetting Chaosnet -
The use of @l[chaos:reset] 
@findex[chaos:reset]
for resetting Chaosnet software is obsolete for most purposes,
but still available because it resets Chaos connections.
To reset the software without affecting open Chaos connections use @see[net:configure][fun].

@item Resetting TCP/IP -
@findex[tcp:start]
@findex[tcp:tcp-disable]
The @l(TCP) functions, @l[tcp:start] and @l[tcp:tcp-disable], are no longer implemented.
Use @see[net:configure][fun] and @see[net:deconfigure][fun] instead.

@item (De)allocating hardware interfaces -
The function @l(si:set-processor-owning-ethernet) has been enhanced to handle both,
or either, type of hardware interface.
Also refer to @see[si:dont-use-3com][var] and @see[si:dont-use-excelan][var].

@item File Transfer Protocol command -
Previously implemented as @l(ftp:cmd),
now named @see[ftp:ftp][fun] and enhanced significantly.

@item Ping -
TCP/IP now answers to ``Ping'' requests,
and can send various Ping requests with @see[icmp:ping][fun].

@item Exos Diagnostics -
These routines have been modified and renamed;
new functions are
@see[ethernet:exos-stats][fun], and
@see[ethernet:netspy][fun].

@end(itemize)

@section Variables

See Section @ref[section-variables], @b(@nameref[section-variables])
for details on networking control/parameter variables.

The variable @b[tcp:dma-initialized-p] is no longer defined.
@vindex[tcp:dma-initialized-p]
Formerly, this variable had to be @l(SETQ)'ed to reinitialize
the Excelan board.
@cindex[hardware initialization]
This is no longer necessary; the
boards are initialized by @l(net:configure).

@section Peek Display

@csubindex[network][statistics]
@cindex[network menu]
A new command mode has been added to the @l(Peek) program.
The @l(Network) command displays status and statistical information
on each network protocol and interface.
See Section @ref[section-peek], @b(@nameref[section-peek]), for details.

@section Messages and Errors

The run-states that may be seen on the Who-Line (or reported by Peek)
during networking operations are documented in
Section @ref[section-messages], @b(@nameref[section-messages]).

Note that the run-state ``Exos reply'' is replaced by ``TCP Socket I/O''.
