[ale] configuring getty for dialin logins

[root]

I'm trying to configure a modem to allow dialin logins on a RedHat 3.0.3 
box.  I've added the following entry to the /etc/inittab file:

# Added to allow logins on the modem on Serial 1
S0:3:respawn:/sbin/getty ttyS0 B38400 vt100


When I tell init to re-read the inittab file with "init q", I get the 
following errors in /var/log/messages:

Jul 31 15:26:28 aleach-pc init: Re-reading inittab
Jul 31 15:26:30 aleach-pc getty[731]: Segmentation fault

Jul 31 15:26:49 aleach-pc init: Id "S0" respawning too fast: disabled for 5 minutes


Additionally, the permisions on /dev/ttyS0 go from crw-r--r-- crw------- 
each time "init q" is executed.  What's wrong?!?!  I've tried to 
understand from the Serial-HOWTO, the RedHat Unleashed book, the relevant 
man pages (getty, inittab, init), and various web sites I found from a 
search, but to no avail...

Thanks for any suggestions...
