Re: [hylafax-users] Help for strange problem in sending fax with 4 port serial IO card

["support" <support@xxxxxxxxxxxx>]

Hi Maurizio.

Does a single port on the multi-port serial card work reliably if you only
have one modem connected ?

Do you know whether the serial card supports an interrupt status register
(if not, can you supply a url to the manufacturers data for the card) ?

Have all of the working installations used a single modem ?  And have all
these modems been connected to the motherboard serial port(s) ?

Are you using identical serial cables and handshaking ?

Are the motherboard and serial card PCI compliant ?  Are they listed on the
PCI SIG's integrators list ?

http://www.pcisig.com/developers/compliance_program/integrators_list/pcix/

Have you tried HylaFAX 4.2.2 ?

serial IO card

Hello,
I have a Debian 2.4 box with Hylafax 4.1.1 and I have made until now quite a
lot of installations all working smoothly.

Just to have more modems to use for sending i bought a cheap multi serial
board with 4 ports on it with four (tested) modems.

During boot the board is regularly recognized Serial driver version 5.05c
(2001-07-08) with HUB-6 MANY_PORTS MULTIPORT SHARE_IRQ DETECT_IRQ SERIAL_PCI
ISAPNP enabled ttyS00 at 0x03f8 (irq = 4) is a 16550A
ttyS04 at port 0x2000 (irq = 17) is a 16550A
ttyS05 at port 0x2008 (irq = 17) is a 16550A
ttyS06 at port 0x1c00 (irq = 17) is a 16550A
ttyS07 at port 0x1c08 (irq = 17) is a 16550A

And with 'lspci -v' it claims to be:

00:0a.0 Serial controller: Timedia Technology Co Ltd: Unknown device
7168 (rev 01) (prog-if 02 [16550])
        Subsystem: Timedia Technology Co Ltd: Unknown device 4056
        Flags: stepping, medium devsel, IRQ 17
        I/O ports at 2000 [size=32]
        I/O ports at 1c00 [size=16]

Here the problem using the new ports (ttyS4 and more):
The box RECEIVES ALL faxes, any type, any number of pages.

But the box CAN NOT SEND any fax: it starts sending regularly, but after a
while it stops sending and errors are various:
- Stop and wait failure (modem on hook)
- No response to MPS or EOP repeated 3 tries
- Failure to train remote modem at 2400 bps or minimum speed

and also others. Most of the errors are on faxes having more than 1 page.
Sometimes faxes with just 1 page are sent.

Just to make things clear, if I try to use ttyS0 (which is on the
system) instead of the new ports everything WORKS fine
