HylaFAX 4.1beta2 on RedHat 6.0 with g++ --version: egcs-2.91.66

My RedHat 6.0 system (HP Kayak XAs - 400MHz Pentium II) has all the
latest errata RPMs applied.

I am using an U.S. Robotics Sportster 56K/x2/v.90 external modem
attached to /dev/ttyS0 (the port labelled serial A on the back).  I
have updated the firmware to the latest version available on the 3Com
website and I have set DIP switches 3, 5, and 8 DOWN (ON) which
enables result codes, disables auto answer, and enables AT command set
recognition.  I can successfully communicate with the modem using cu
or minicom; here is a transcript of a cu session.

$ sudo cu -l /dev/ttyS0
Connected.

I know Sportsters aren't great fax modems, but the problem I'm
encountering happens even before faxgetty has a chance to read
anything from the modem.  I've used the modem successfully with a
commercial fax package, and this very same problem happens as well
when I try to set up HylaFAX on another RedHat Linux 6.0 computer with
a completely different modem from another manufacturer.

I fetched

ftp://ftp.hylafax.org/pub/hylafax/hylafax-4.1/source/hylafax-4.1beta2.tar.gz

unpacked the tar file;

ran ./configure and accepted all the default values;

built and installed with make all; su; make install;

ran /usr/local/sbin/faxsetup (as root) and accepted all the default
values (I did enter my area code though);

let faxsetup start up the servers and run faxaddmodem for me;

told faxaddmodem to look for an external modem attached to ttyS0;

accepted all the default values offered by faxaddmodem except for the
area code, the fax line's phone number, server tracing (which I
changed from 1 to 0xffffffff so that I could include debugging
information which might or might not help narrow down the problem),
and ClocalAsRoot (which I set to yes to rule out whether it might help
or not - it didn't help whether it was "" or yes);

let faxaddmodem, which recognized the U.S. Robotics Sportster 56K
modem, use the usr-2.0 defaults to set up /var/spool/etc/config.ttyS0;

told faxsetup there wasn't any more modems to set up;

and let faxsetup run faxmodem ttyS0.

Watch closely, this is where the problem happens.  I cannot get
faxgetty to run, either from /etc/inittab or by hand.  When I try to
run it by hand as root,

/usr/local/sbin/faxgetty ttyS0

faxgetty opens the serial port, sends an initial AT command string,
and tries to read a response but fails to read anything and times out.
This happens even though /dev/ttyS0 would appear to have the proper
permissions,

crw-------   1 uucp     uucp       4,  64 Sep  9 15:29 /dev/ttyS0

and cu, minicom, and a commercial fax package all can open the serial
port and talk to the modem just fine.  Even faxaddmodem was able to
interrogate the modem.  So why is faxgetty hanging and giving me so
much trouble?

Here are the server tracing messages that were sent to syslog:

I've searched the mail archives and found other people who have posted
similar problem reports, but I haven't seen a solution.  If you have
encountered this problem or have an idea what causes it, will you
please tell us how to make faxgetty work?
