0.90    First release

0.91    Provide one extra connection so that lpq requests can get
	through and return status. Lprm requests fail; they make no
	sense.

	Display IP address of client.

	Rudimentary security. Server and client must both be on same
	subnet. Can be disabled with -s option.

	More security; allow and deny IP lists.

	Distribution includes lpr.pl for the ifilter and banner.pl for
	the ofilter on Berkeley LPD systems.

	Announce available printers with tones: C,D,E

0.92    More information on lpq status: on/offline, paper out.

	Option -n to override number of printers reported by BIOS.

	Option -lhostip logs startup message and status changes to
	syslogd on host.

	Fixed bug in lpr.pl. Was sending out data file again as control
	file. Remnants of test implementation. Made lpr.pl unworkable
	with standard LPDs and also wasted channel capacity.

0.93    Report jobname, username and hostname on completion of job.

	Use name resolution so names can be specified for -a, -d and
	-l.

0.94    Conformance to RFC1179. Control and data files in either
	order.  Use N for jobname rather than J. Limits on username and
	hostname now conform to RFC. Jobname truncated to 31 chars
	though.

	Respond to long query request as for short query.

	Changes to lpr.pl to match. Try to use ports 721 to 731
	inclusive.  Naming conventions for data and control files as
	RFC.

0.95    Add -j option to select direct (telnet-like) protocol. Just
	a raw byte stream, ended by closing the connection. On port
	9100+n (n=0,1,2) by default.

	Provided jd.pl to send data by direct protocol.

	Fixed harmless comparison operator bugs in lpr.pl.

	Fixed bug in lpr.pl where control and data were using same
	count of bytes because same variable was used.

	Improved buffering strategy: if printer is busy, keep
	collecting data as long as there is room in buffer. Allows
	clients that send small packets to continue sending without
	being blocked by printer handshake.

0.96	Fixed bug where server closed connection before printing everything
	in direct mode. Doesn't happen in lpd mode because of handshake.

	Forgot to provide jd.pl in last release.

	New program jd.exe, a DOS client for direct protocol.

	Use DOS LPT to COM redirection in conjunction with TSRCOMM,
	an interrupt I/O serial driver. See documentation in LPTCOM.ZIP.

	Provided documentation in pprd.doc and jd.doc.

0.97	Added -i option to pprd to reinitialise printer via hardware line
	when job aborted via C-Fn keys.

	Send a reset via sock_abort when job cancelled from console so
	that client will receive notification of a broken connection.
	Lpr.pl and jd.pl changed to take note of this.

	New program jdlprd.pl for Unix systems to provide a jd to lpr
	gateway so jd.exe can send jobs to Unix also.

	Harmless typo in jd.pl.

	No need to call tcp_shutdown() in jd.c. It will be done by
	atexit().

0.98	Bug in pprd.c. Under some circumstances, PPRD may miss a EOF
	from the client, leaving it stuck in the protocol.

	Bug on lpr.pl. Forgot to adjust length to send EOF byte too.

	New feature. Printers can be assigned names in wattcp.cfg.
	Defaults are lpt[123].

0.99    For printing via BIOS, interface will not be ready after the
	print call, so check again. Should be able to batch the
	bytes better.

	Direct write to hardware port can be selected by -b. Should
	be able to handle fast interfaces better than BIOS. Won't
	make much difference with slow printers because the bottleneck
	is the printer in that case.

	Moved most operation instructions out of README.  Documentation
	in nroff format. Printable version supplied.
