This document describes the changes made to the software between the
<I>previous</I> and <I>current</I> versions (see above).
If you don't find something listed here, then it was not done in this
timeframe, or it was not considered important enough to be mentioned.

<A NAME="general"><B><FONT SIZE=+3>G</FONT>ENERAL CHANGES:</B></A>
<UL>
<LI>the LucidaTypewriter font typically used for imaging tag lines
in outbound facsimile is now included in the source distribution
<LI>the old <TT>ModemFlowControlCmd</TT> modem configuration
parameter has been replaced by new
parameters <TT>ModemHardFlowCmd</TT>, <TT>ModemSoftFlowCmd</TT>, and
<TT>ModemNoFlowCmd</TT>
(<STRONG>NOTE THAT THIS IS AN INCOMPATIBLE CHANGE</STRONG>)
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
<UL>
<LI>a new configuration directory <TT>DIR_SBIN</TT> was added; it is the
target for many executable programs that used to be placed in
<TT>DIR_SPOOL/bin</TT>
<LI>BSDI 2.0 is now recognized
<LI>problems handling SunPRO C++ compilers have been corrected
<LI>various mods for SCO
<LI>various mods for the DEC Alpha running OSF
<LI>fix for configuring proper serial port handling support on AIX systems
<LI>a check was added for a missing <TT>getutent</TT> function delcaration
<LI>workaround for finding getty on SVR4-style systems
<LI>workarounds for shells that do not properly implement function return codes
<LI>the default lock file scheme is now setup for Solaris 2.x systems
<LI>manual page processing was corrected for AIX systems
<LI><TT>bsd-*-strip</TT> style manual page handling was corrected
<LI>the <B>lockname</B> program is now automatically installed (you used
to have to do this manually)
<LI><B>port/syslog.c</B> has been updated to handle systems that do not
support UNIX domain sockets (e.g. SCO)
<LI><B>port/seteuid.c</B> and <B>port/setegid.c</B> have been updated for SCO
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="modemconfig"><B><FONT SIZE=+3>C</FONT>HANGES IN THE MODEM CONFIG FILES:</B></A>
<UL>
<LI>the old <TT>ModemFlowControlCmd</TT> modem configuration
parameter has been replaced by new
parameters <TT>ModemHardFlowCmd</TT>, <TT>ModemSoftFlowCmd</TT>, and
<TT>ModemNoFlowCmd</TT>; the appropriate command string is sent to
the modem based on the current flow control scheme (the setting of
<TT>ModemFlowControl</TT> in the prototype config file now becomes
a <EM>default</EM> setting to use)
<LI>many files have been renamed because it is no longer necessary to
have separate files per flow control scheme (unless there are significant
differences in the configuration parameters)
<LI>a typo was fixed in usr-courier-xon
<LI>a new file was added for modems based on the Cirrus Logic chip set
(e.g. the internal modem sold with WinBook XP notebook computers)
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxq"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXQ:</B></A>
<UL>
<LI>jobs are now typed as one of: <I>facsimile</I>, <I>pager</I>, etc;
this is used to decide which transmit agent to use and in formatting
notification messages
<LI>a potential security hole in the document file handling has been corrected
<LI>external commands invoked no longer inherit any open file descriptors
except <TT>stdin</TT>, <TT>stdout</TT>, and <TT>stderr</TT>
which are directed to <B>/dev/null</B>
(<EM>beware this can cause problems with some shells</EM>)
<LI>a <TT>QUIT</TT> message (as sent by <B>faxquit</B>) no longer
causes immediate termination; processing is delayed until any
active jobs complete
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxsend"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXSEND:</B></A>
<UL>
<LI>the current flow control scheme is now used to select which of
<TT>ModemHardFlowCmd</TT>, <TT>ModemSoftFlowCmd</TT>, and
<TT>ModemNoFlowCmd</TT> to send when setting up DTE-DCE flow control
<LI>a bug was fixed for AIX whereby flow control was potentially not
being initialized properly
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxgetty"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXGETTY:</B></A>
<UL>
<LI>a bug was fixed in the Class 2 driver that caused the server to
hang when a premature <TT>NO CARRIER</TT> result was received
<LI>a bug was fixed for AIX whereby flow control was potentially not
being initialized properly
<LI>external commands invoked no longer inherit any open file descriptors
except <TT>stdin</TT>, <TT>stdout</TT>, and <TT>stderr</TT>
which are directed to <B>/dev/null</B>
(<EM>beware this can cause problems with some shells</EM>)
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="pagesend"><B><FONT SIZE=+3>C</FONT>HANGES TO PAGESEND:</B></A>
<UL>
<LI>text messages are now stored in a file; this corrects problems
where, for example, you could not include ``:'' in a message
<LI>jobs with no destination PINs are now rejected without placing
a phone call
<LI>protocol tracing has been significantly improved
<LI><TT>PagerSetupCmds</TT> are now sent to the modem after it is placed
into Class 0
<LI>a bug has been fixed that caused various configuration parameters
to not be correctly initialized (e.g. <TT>IXOService</TT>)
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxaddmodem"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXADDMODEM:</B></A>
<UL>
<LI>many missing server-related configuration parameters are now
recognized and correctly propagated from old config files
<LI>several missing modem-related configuration parameters are now
recognized and correctly propagated from prototype config files
<LI>the faxq config file checking has been fixed up
<LI>several obscure server-related parameters have been removed from
the interactive prompts; to change them you must edit the config file
<LI>the DCE-DTE flow control scheme can now be specified as ``default''
and an appropriate selection will be chosen
<LI>the logic used to select a prototype configuration file now matches
the flow control scheme using a regular expression instead of a straight
string match (means many prototype config files can be merged)
<LI>the message about starting faxq now prints the correct argument to
supply on the command line to faxq
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="sendfax"><B><FONT SIZE=+3>C</FONT>HANGES TO SENDFAX:</B></A>
<UL>
<LI>a <TT>-N</TT> option was added to specify no notification
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="sendpage"><B><FONT SIZE=+3>C</FONT>HANGES TO SENDPAGE:</B></A>
<UL>
<LI>the command line interface has changed; only a single
text message can be specified and PINs are now specified with a new
<TT>-p</TT> option
<LI>a <TT>-N</TT> option was added to specify no notification
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="utility code"><B><FONT SIZE=+3>C</FONT>HANGES IN THE UTILITY CODE:</B></A>
<UL>
<LI>some problems in <TT>probemodem</TT> have been corrected
<LI>changes for compilation on SCO systems
</UL>
