Conexant Soft56 modem won't connect

Conexant Soft56 modem won't connect: Posted by bob olbrich on November 12th, 2003; Hello,

I can't get my Conexant SoftK56 modem to connect
to my ISP through HyperTerminal in Win98SE or by
creating a dial-up connection. I've tried many
init strings and lower speeds, but I always get
a "no carrier" response. The command AT#UG reveals
the termination cause to be "retrain failed"
Can anyone help interpret my reports ?

Thanks for any help,

Bob; Posted by Aaron Leonard on November 12th, 2003; Well, this is odd. You really ARE training successfully
on all calls - in V.34, with a receive rate of 26400 -
and are successfully negotiating LAPM (V.42).

The "CONNECT 19200" message is because the modem is configured
to report DTE speed rather than DCE speed, and because Windows
is configured to set the COM port to 19200 bps. I ASSUME this
is of only cosmetic concern; however it is conceivable that something
might change if you were to set the DTE speed to 115200. (The
nominal DTE speed SHOULD only be cosmetic, as the SoftK56 is an
HSP modem and doesn't use a physical COM port.)

Anyway, it seems that, immediately after the call trains, your modem
requests a retrain; this retrain attempt fails, and your modem hangs
up. Normally this would be because it is seeing a poor signal - but
if this REALLY were the case, then you wouldn't be able to train and
negotiate LAPM consistently in the first place.

So ... I suppose I'd try something like this:

- set the DTE speed to 115200; couldn't hurt

- try dropping your modulation down to V.32bis or even V.22bis
(AT+MS=V32B, AT+MS=V22B) and see if you can get this to work at
all

- see if you can find a modem code upgrade

- try a different modem

Good luck,

Aaron
