Re: [hylafax-users] failure to receive silence

["Andrew Rinaldi" <andrew.rinaldi@xxxxxxxxxxxx>]

Hi,

I would just like to add that in my experience 'software' modems are
unsuitable when a reliable fax solution is required.  I believe other people
have said the same thing recently.

Link that sells the USB modem (sorry it's in greek, I couldn't find any
other site for it):
http://www.e-shop.gr/show_per.phtml?id=PER.533709

lsusb recognizes it as:
Bus 001 Device 002: ID 0483:7554 SGS Thomson Microelectronics 56k SoftModem
  idVendor           0x0483 SGS Thomson Microelectronics
  idProduct          0x7554 56k SoftModem

The driver I used is the 'slusb' SmartLink driver (google for
slmodem-2.9.11-20070813.tar.gz)

The modem is installed under /dev/ttySL0. I didn't have to reconfigure
hylafax for it, I used the same config file as before for the PCI softmodem
(basically configured as a generic Class1 modem, as in
/var/spool/hylafax/config/class1).

	For the error you are getting now I would search the archives of
	hylafax mailing list.
	
	Could you share some info on the smart link usb modem.
	Link to a website that sells it?
	How did u setup hylafax ? what was the ttyS? or
	What drivers you are using? Most of the usb modems were wind modems
so
	is this one a regular modem or are u using windows drivers?
