Modem not recognized

[Winfried Truemper <winni@xpilot.org>]

Setup:	HylaFAX v4.0pl1 under Linux 2.0.29 with gcc 2.7.2; 
	USRobotics Sportster Vi 33600 Faxmodem on /dev/ttyS1

The command faxstat prints:

	HylaFAX scheduler on hermes.tc.de: Running

But no modem is recognized. I configured HylaFAX with faxaddmodem/faxmodem 
and I would expect

	HylaFAX scheduler on hermes.tc.de: Running
	Modem ttyS1 (+49 221 9252NNN): Running and idle

After double-checking my setup I decided to generate debug messages. Via
syslog I only get

	May  4 22:12:11 Hermes HylaFAX[4907]: HylaFAX INET Protocol Server: restarted.
	May  4 22:12:11 Hermes HylaFAX[4907]: HylaFAX Old Protocol Server: restarted.
	May  4 22:12:11 Hermes HylaFAX[4907]: HylaFAX SNPP Protocol Server: restarted.
	May  4 22:14:34 Hermes FaxQueuer[4928]: HylaFAX (tm) Version 4.0pl1

so I decided to use "strace" to track the error down. I get mysterious
messages when stracing "faxstate":

	chdir("/var/spool/fax")                 = 0
	open("FIFO.ttyS1", O_WRONLY|O_NONBLOCK) = -1 ENXIO (No such device or address)

Similar messages appear when stracing "faxq":

	4161  chdir("/var/spool/fax")           = 0
[..]
	4162  stat("FIFO.ttyS1", {st_mode=S_IFIFO|0666, st_size=0, ...}) = 0
	4162  stat("etc/config.ttyS1", {st_mode=S_IFREG|0644, st_size=3299, ...}) = 0
[..]
	4162  open("FIFO.ttyS1", O_WRONLY|O_NONBLOCK) = -1 ENXIO (No such device
or address)

But the file is definetly there:

	dir /var/spool/fax/FIFO.ttyS1
	prw-------   1 uucp  uucp   0 May  4 22:01 /var/spool/fax/FIFO.ttyS1

Does anybody encountered a similar behaviour under Linux? What's going
wrong? I'm using libc 5.4.20.

Thanks in advance
