I decided to try along with you. I grabbed an old abandoned laptop from 
work (Zeos 486, 8M of RAM, 80M hard drive, external floppy), and made a 
null modem cable.

I did about the same, but route add shouldn't be required.
The trick it turns out to have both machines connected, and running before 
you bring up the interface on either.

Snipped down to the commands I had to use. The only thing I found that 
needed to be changed is the ipconfig syntax. Busybox uses an older 
ifconfig, it seems.

The command on the laptop needs to be:
 ifconfig sl0 192.168.1.2 dstaddr 192.168.1.1

I see the same thing in the logs on both machines. ttyS0 works for me, 
though.

Now, more detail. I got it working, and managed to nfs mount the rpms. 
However, it timed out everytime. Regardless of various nfs options, it 
times out just trying to get a directory listing of 
/mnt/cdrom/RedHat/RPMS. I can get as far as listing /mnt/cdrom/RedHat/, 
but even that is slow.
After a lot of wasted time, I gave up.

Then, I decided to try an HTTP install. Due to disk space problems on the 
laptop, I only allowed the installer to run through the copying of disk2, 
and doing the pivot root. Then I killed the installer, and ran the rpm 
commands manually so I could select only a bare minimum of packages.
It's installing slowly now. The downloading of glibc-common has taken over 
a half hour so far, and it's just half done. I believe I've done 5 or 6 
packages so far. :)

I'll let the install continue, but having seen the results, this isn't an 
install method I plan on supporting in any fashion. :) The slip network 
link is just too slow. If I rebuild the kernel and include cslip support, 
it might help, though I'm not sure of even that.
