Jerry,
With the limited info available, my best guess would be that you do not
have a kernel with Serial Port support compiled in. Check the Dachstein ftp
site for a kernel with serial port support.
If this is not the problem please follow the guidelines for providing us
info to assist you further...

Best of luck,
Steve

Subject: [leaf-user] Serial port problem. Checked Howto/Faq/List
Archive.
I am attempting to run a Dachstein image on a system
that will eventually not have a keyboard and monitor.
I'm actually having great fun with it this weekend,
but there is one thing I can't seem to resolve without
help.
Following the Howto's and FAQ's, I run into a problem
almost immediately. When I type the example echo from
the guides,
# echo "Hello World" > /dev/ttyS0
I get in return
cannot create /dev/ttyS0: error 19
The device is in fact there when I do an ls, which is
reaffirmed by my later actions (please see below).
I went ahead and took the other steps except
attempting to get the boot messages to show up on
ttyS0 (which I am not expecting to do. read that
thread too). I examined all the related mailing list
threads, and acted on the advice there as well.
Specifically, I did the following:
-placed a copy of serial.o in /boot/lib/modules
-edited /boot/etc/modules and added
serial
-edited the inittab serial line example to say
T0:23:respawn:/sbin/getty -L ttyS0 19200 vt100
-added ttyS0 to the securetty file.
-attached another computer with a terminal emulator to
com1 via a null modem connector and serial cable.
-backed up all my changes and confirmed that they were
still there after I rebooted.
-added console=tty0 console=ttyS0,19200n8 to the
append line in syslinux.cfg
-at one point added the following
serial 0 19200 0
to the top of my syslinux.cfg file too. That caused
the DF logo and initial info to show up on the
terminal, so I know the cable connection and baud rate
is fine. But it stops there (no prompt). It also
caused an "Unknown keyword in syslinux.cfg." error, so
I removed it.
needless to say, I get the Id "T0" respawning too
fast... message too. But I believe this is a result of
the first "error 19" issue I mentioned.
Any help on what appears to be the last issue I have
managing this system by serial connection would be
extremely appreciated.
