Anyone know of an answer or another method ?



Thanks.



For dialup, you connect the modem to the dialup modem

pool, and run it long enough to train up the modem and

evaluate the frequency bins. So you must use a dialing

string, hear the "tones" coming from the modem speaker,

and connect until the ISP delivers a prompt. Wait

60 seconds (or, whatever period the ISP leaves the

unauthenticated session connected). Then, drop the connection,

and use a Hayes AT command to dump the table.



In this example, they connect to the modem pool for

15 to 60 seconds. Then disconnect. Then, manually

type an AT command.

I had a worked example of this (run on my USR dialup modem),

but can't seem to find any evidence of it. It gives

some info per frequency bin, and the site I got the

info from, showed some typical curves. The ATI6 command

in the above example, is a summary of conditions,

of some sort. But it should be a summary of the

last "session", that 15 to 60 seconds of "training"

the modem got. Some other command gives the values

for the bins. But I can't even find my Hayes command

set document. I've got one somewhere, for that modem.

Just can't seem to find it.

Thanks.

I don't have an ISP, I use a wireless receiver that uses my apt. account for internet.

I know that I was using hyper terminal at one time with AT commands.

You don't they they broke it ? Just kidding.

My telco is coming out in 2 weeks to check my line.

I can fax fine, but would like some proof of the poor line quality.

I have already check the internal wiring.

The telco gives instruction on how to verify if the static is internal or external by plugging into the outside box.

When I checked, it was inaccessible.

In addition to phone wires, there were cable lines going into the box, so no telling "what's in that box."

There may be a lizard or gecko remains in there partially shorting out the phone lines. :-)

When squirrels in my "hood" venture on to the power lines, a transformer trips.

Take care.
