Further to the above, I recompiled the kernel with both PnP and ppp support
included (in the kernel, NOT as modules) and set the BIOS setting to "Yes".
I logged in as root and tried:
# setserial /dev/ttyS2
I got
/dev/ttyS2: port 0x03e8 irq 10 uart 16550A
HURRAY!
I then tried to dial up to my ISP using minicom instead of pppd (thus
bypassing any permissions issues on minicom). Minicom politely informed me
that the modem was off-hook. I issued a "ctl-A h" command to hang up the
modem and then tried to dial again after resetting the modem. Same results.
It now appears that the group of suspects has been narrowed down to the PnP
initialization interaction between my kernel and ROM-BIOS. Unfortunately,
I'm kind of stuck about where to go from here. Can anyone give me a
sugggestion about how to cause the modem to complete it's PnP initialization
and come online in a ready state?

I have installed RH6.2 on a new PC.
I also downloaded and ran the Bastille hardening script, but I have
not proceeded to do anything about the result of the Bastille script
yet (I assume that I have to do something to enable the protection).
This is partly because I did not really understand some of the
questions asked so I decided to let that wait.
Now I have connected the PC to my internal LAN in order to start
working on the networking part of it. It answers ping OK.
But I cannot telnet to the PC from my WinNT machine and when I look at
the ipchains setup it lokks like this:
# ipchains -L
Chain input (policy ACCEPT):
Chain forward (policy ACCEPT):
Chain output (policy ACCEPT):
To me this looks like it will accept anything for now (what I
expected). So why does it refuse telnet? Where is that set up?
Or do you have to explicitly *enable* telnet after the RH6.2 install?
please advice
