HSF (softmodem) Driver FAQ (Frequently Answered Questions)
1) I have an HCF modem. Can I use these drivers?
No, these drivers are only for the Conexant HSF (softmodem)
family, not for the HCF (controllerless) chips.
HCF drivers are available from http://www.mbsi.ca/cnxtlindrv/hcf
2) The modem returns "NO DIALTONE" when I try to dial
Please check your line cord and country settings (with hsfconfig --country).
If they are correct and the "NO DIALTONE" problems persist, you
may try disabling dialtone detection with the "ATX3" command.
If this still doesn't work, you should report the problem to us.
3) The modem returns CONNECT messages with bogus connection speeds, like
"CONNECT 9600" or "CONNECT 115200"
Use "ATW1" to enable reporting of line speed, error correction protocol
and DTE speed. See the command set reference manual
(100498D_RM_HxF_Released.pdf) for details.
4) The modem works, but I can't hear anything when dialing
Please check the Ln and Mn settings in AT&V. They should be L1 and M1.
If not, change them with the command: ATL1M1&W
If you still cannot hear any call progress sounds, and use a
modem model that does not have its own speaker (such as on a notebook),
verify your audio mixer settings (using aumix or equivalent utility) to
ensure that the volume levels are high enough and that the "honeIn"
channel is not muted.
On modems (such as many MC97 units) requiring that call progress sound
be extracted in software by the driver and played through the normal
sound subsystem, no sound is presently available. We hope to implement
it one day.
5) My modem's PCI ID is 127a:1025 or 127a:2005 and it doesn't work
You probably should try the HCF driver. Some early HCF modems are
incorrectly identified as HSF in some versions of the PCI ID lists
used by lspci and the linux kernel. Also, a few modem vendors have
tried to save costs by omitting the EEPROM where device IDs are stored,
causing the same default ID built into the bus interface chip to be
used for both HCF and HSF devices.
6) Changing serial port parameters with "setserial" on ttySHxF0 or /dev/modem
doesn't work.
Since this modem driver provides a virtual serial interface, which
is not directly connected to a physical UART like a normal serial
port, it is not possible and would not make sense to configure
it with "setserial". Therefore you shouldn't use this command
on the ports associated with this driver.
7) I installed the driver, and now the /dev/ttySHxF0 or /dev/modem device is
supposed to be there but it doesn't exist.
On devfs-based systems (such as Mandrake), the missing device
node is often a sign that the driver modules didn't load or initialize
properly. Try "modprobe hsfserial", then check the /var/log/messages
file or or run "dmesg" to see any kernel error messages that could
provide a clue as to why loading of the driver failed.
8) I have an ACPI-based machine and the driver is crashing or not loading
It might be necessary to recompile a generic kernel from
ftp.kernel.org with the latest ACPI (and perhaps also
KACPID kernel lost interrupt) patches from
http://sf.net/projects/acpi/
9) The modem disconnects or the system crashes as soon as or shortly after
I start the graphical desktop (X, GNOME, KDE, etc..) or use the sound card.
Some users have reported conflicts between certain sound card drivers,
(especially AC97 devices) and our modem drivers. Most graphical
desktops access sound devices when starting up.
We are investigating these problems and are hoping to find solutions
soon. Meanwhile, we recommend disabling any conflicting modules while
you use the modem. If you experience a conflict, please report it. |
