There are plenty. Take a look at Kenton Lee's website at
http://www.rahul.net/kenton/xsites.html
He lists a boatload of X servers for NT/W98/W95, along with everything
else you would want about X.

You might want to look up the stuff in "The Bell System Technical
Journal". You may need to consult a good technical library to get
these, possibly on inter-library loan. This is a two-volume issue and
you will probably want both volumes. I no longer remember what is in
each volume.
M.D. McIlroy, E.N.Pinson, and B.A. Tague "Unix Time-Sharing System
Forward", The Bell System Technical Journal, July -Aug 1978, vol 57,
number 6 part 2.
Thompson, "Unix Implementation", "The Bell System Technical Journal,"
vol 57, No. 6, July-August 1978.
I have "the Linux Kernel book" by Card, Dumas, and Mevel from John
Wiley (even contains Red Hat Linux 5.0 CD-ROM [obsolete] in the back).
You might want to borrow it before you buy it because it may not be
quite what you want.

Look in your /etc/lilo.conf file. make sure the values timeout=XX and
default=label are correct and present, where XX is the number of secs to
timeout to the default, and label is the label for the image you want to be
default.

Modem not receive and send faxs
Hello All!
I have a problem. I am using Red Hat 5.2 on my server and HylaFax as
fax-program. I have modem Zyxel U1496E+, it's good fax-modem. When I am
working in Internet, the modem's work is fine. But when I want to receive
or to send the fax, modem do not work! Transfer is beginning, run,run, and
... error!!! The connection is dead. And this situation each case is
repeating. I think, I incorrectly made settings of Hylafax or faxgetty, or
modem.
If You can help me, I shall be very grateful! In Russia not enough
information about Linux, Hylafax, etc!
Best regards!

Two other very good options:
- John Lions' "Lions Commentary on UNIX 6th Edition, with source code"
grapples with a fairly early version Unix, and was, for years, the
only available kernel documentation;
- "The Design and Implementation of the 4.3BSD UNIX Operating System"
by Leffler, McKusick, Karels, and Quarterman.
Obviously biased towards the BSD variations, but nonetheless
contains a _lot_ of useful technical material. And the BSD
implementations had considerable influence on later Unixes, so this
is hardly going to steer the reader to dramatically _wrong_
material.
I would tend to think that both of these might be a slight bit more
precisely directed to M. Smith's needs than the works you mentioned.
Not dramatically so...

He said free. Kenton's page only lists those that have to be purchased, except
for Cygwin, but is is not complete. It currently will not run on on Win95/98,
only WinME, Win2000, and NT.

If you find out, let us know. I got aggravated by this sort of thing
a while back and wrote a brief script to do it. Obviously you're looking for
a C solution, not a shell one, but the methodology will be the same -
while (specified process is found in process table)
{ sleep for a while and check again }
# good, we fell out of the loop
continue with program...
Shouldn't be too hard. My interpretation of it is at

Recompiling your kernel won't recreate /dev/null
I can tell you two different ways to recreate /dev/null
1) as root,
cd /dev
./MAKEDEV std
2) as root
mknod /dev/null c 1 3
chown root:sys /dev/null
chmod a+rw /dev/null

Hmmm... I'm currently runnin MI/X on both Win98 and WinNT (free)
and Hoblink X11 on Win98 (again free)
Both are listed on Kenton's website. Perhaps you didn't look hard

Sorry but his is really funny, you deleted /dev/null, once I read an amusing
aricle somewhere, which stated: For decades UNIX sysadmins had been directing
files to /dev/null an now it would be full...:-)
Honestly, you don't need to recompile your kernel, not even reboot...:-)
you can create a new /dev/null with mknod
crw-rw-rw- 1 root root 1, 3 Jun 24 2000 /dev/null
mknod --mode=0666 /dev/null c 1 3
Should do the trick...:-)
Good luck
