[hcflinux] HCF - loss of Connect speed

[Linuxant modem support]

Hi,

try to force a V.34 connection on both sides of the connection. 56k
modulations (K56Flex, V.90, V.92) require a digital line and modem on the
server (usually an ISP) side.

The AT command should be "+MS=V34".

You can also run the following command in a root console to get a little bit
of diagnostic information on the HCF modem side:

cat /proc/driver/hcfpci/0/lastcallstatus

Hi --

Newcomer, here.  I have a dedicated analog phone line connection to a
dedicated Linux SMP server, with an HCF modem I've never seen,
installed in the server box.  On the 'home' end, a V90-upgraded
external Motorola ModemSURFR (with a Rockwell chip; it was a K56flex
modem originally, but not any more).

With the full driver successfully installed on the server, I was
initally seeing 33.6 connect rates on both sides of the connection.

Now, though, I'm usually seeing 28.8 on the server HCF side, and can't
seem to persuade it to return to the 33.6 connections it was making
earlier.

I'd half-suspect it has something to do with changes to init strings I
threw at it, while seeking the "most up-to-date" performance it was
capable of.  Assuming -that's- the problem (versus, say, phone line
degradation), what should I do/try, to bring back the 33.6 connections
I was seeing just a week ago...?

Thanks kindly,
