JASSPA's MicroEmacs is available from:-
http://www.jasspa.com.
This will run a 'cygwin' session in a buffer window etc. Cuts
and pastes using X-Windows type selections. Also runs on Linux.

My experience is with the ESC 400, not the ESC 440, so I can't promise
this will help; but....
If you're using the old stcolor driver, you need to add "-dSoftweave
stcolor.ps" to the extra Ghostscript options line in Red Hat's printtool,
or otherwise add them to the Ghostscript command line if you're setting it
up in some other way. The stcolor driver isn't compiled by default on many
recent Ghostscript distributions, but you can get a binary version with
this driver from http://www.users.dircon.co.uk/~typhoon/. If you prefer
not to muck with stcolor, you may be able to get it to work with the
uniprint driver by using the 720 dpi upp file for the ESC 500 (I don't
recall the exact filename; browse through the upp files until you find the
right one). On my ESC 400, though, the uniprint driver is
****GLACIALLY**** slow when used at 720 dpi in this way -- it appears to
print one line per print head pass, vs. however many lines the ink
cartridge contains when the stcolor driver does the job.

Preformatted Macintosh Zip disks include a partition table. Unless there's
something about hformat that's not obvious, what you've done is to place
an HFS filesystem on the Zip disk *WITHOUT* writing a partition table to
the disk. I recommend you use a Macintosh (running MacOS) to do this task
in the future. If you want to quickly wipe all the files, you can do it
from Linux by specifying /dev/hdb4 rather than /dev/hdb -- but **ONLY** if
your Linux kernel includes support for Mac-style partition tables. If that
support is lacking, /dev/hdb4 won't map to anything.

Is /dev/ttyS2 (COM3:) using a shared interrupt? If so, try reconfiguring
it to use a non-shared interrupt. Such a configuration might require
passing special parameters to the kernel or the serial port drivers, which
might be a nuisance.

I'm not sure what you mean by "blinking," but my first guess is that the
video modelines are configured in such a way that the screen isn't
properly centered, or is being driven at the very edge of your monitor's
limits. You may be able to fix it by adjusting your monitor's controls, or
by slightly reducing the horizontal and/or vertical refresh rate ranges in
your XF86Config file (in /etc/X11, I believe, on Red Hat distributions).

You probably have the required code compiled as a module instead of as part
of the kernel. I forget the exact name of the option to which I'm refering.

I found these attempts which started today with the first attempt
starting before the time shown here in the first line. As you can see
they are trying to connect one port at a time in order from 3400 up and
at the present time they continue to try diferent ports in numerical
order. I have blocked all connections TO and FROM these addresses but my
logs and tcpdump show that the attempts continue and were still going
when this was posted to redhat.security.general and many other
newsgroups.

Your calculation iw just plain wrong. First, most of the power is converted into
mechanical motion, some amount is lost to resistance in the motor coils and
switching circuits, but if it were all converted into heat, the fan would not
rotate. Second, 4.8W from the power supply does not imply that the power supply
disipates 4.8 watts. These are switching supplies, IIRC the heat output is
not just a linear function of the ouput current.

ldconfig(8) updates /etc/ld.so.cache and some symbolic links. These
usually don't change between the last time the system was working and
(the next) boot time.

Subject: Help: Linux Upgrade Questions
Date: Tue, 25 Apr 2000 21:43:07 GMT
Hi,
My PC is already running Red Hat 5.2, now I am thinking of upgrading it
to 6.1 or 6.2.
My question is do I have to delete everything before installing a new OS
? or is there an upgrade option available ?
Can I upgrade my Red Hat 5.2 to SuSe (ex) Linux ? If upgrade is
available, will it recognize the Red Hat 5.2 ?
Any help is greatly appreciated. Thanks.

You are most likely correct about this. I went rooting through my archives
and found the data sheet on my old Teac 1.2M drive - it says the same thing
as the specs for the newer one, i.e., 360K is read-only. I also found the
old IBM-AT Users Guide which says that a 360K diskette written with the 1.2M
drive will thereafter only be readable on the 1.2M drive. So it's probable
that the (later) BIOSes (or DOS?) solved the problem by writing a double
track - the FD controller looks like a pretty dumb card in itself.
It'd be interesting to determine whether the Linux FD driver does the same
thing. It's academic for me at this point as I no longer have a 360K-only
drive, but it's nice to know what's going on.
