I am running a stock Debian kernel:

Linux version 2.4.26-1-686 (herbert@gondolin) (gcc version 3.3.3
(Debian 20040401)) #1 Sat May 1 18:04:05 EST 2004

I have the following in dmesg:

Serial driver version 5.05c (2001-07-08) with HUB-6 MANY_PORTS
MULTIPORT SHARE_IRQ SERIAL_PCI enabled
ttyS00 at 0x03f8 (irq = 4) is a 16550A

However, no ttyS00 shows up in /dev.
I did a "MAKEDEV update" but it still did not show up.
Maybe I have to do a "mknod /dev/ttyS00 -c " but I have no idea what
the major and minor numbers are. Am I on the right track?
Thanks for any help.

Look for /dev/ttyS0.

Nope, "ls /dev/ttyS*" shows nothing.

ls -l /dev/ttyS0*
crw-rw---- 1 root uucp 4, 64 Nov 2 14:42 /dev/ttyS0

There are your major and minor numbers.

What shows as ttyS00 in boot log _is_ /dev/ttyS0 (ignore leading zero in #
of ttyS# in boot log). Similarly ttyS01 in log would be /dev/ttyS1.

Thanks, I created /dev/ttyS0. Now I have to see if it really is there.
I will find a modem and report back.

Great /dev/ttyS0 now works. Thanks everyone. I still think init should
have taken care of this.

Perhaps you should read the init(8) man page and tell us why you think
that.

init calls /etc/init.d/makedev.
