Well, I am currently connected to the internet
from Australia via a Puretek Netcruiser winmodem
(model PT-3515, Rockwell RS56-PCI R6793-12 HSF
chipset), using the Olicom driver, RedHat 6.2,
and kernel 2.2.14-5.0 ...

I found that setting the vendor and device ids
(127A & 2005) in the lin_hsf.inf file was all
that was strictly necessary to get the beast
to work. That is, without any hacking of the
OEM or Country parameters/flags, my modem will
talk to minicom and dial out and establish a
PPP connection. (Why this should be so, and
whether other things in lin_hsf.inf should be
changed anyway, I haven't yet figured out.)

Of course, before dialling you need to do some
initialising. This stuff works for me:

 AT&FE0V1S0=0&C1&D2+MR=2;+DR=1;+ER=1;W0
 ATS7=60L0M1+ES=3,0,2;X4
 AT+MS=V90

Hope this is useful.
