She is using a Rockwell chipset internal modem. Here is a bunch of her sh
sess data that
I have had a cron job gather.

She is about 45000 feet from the telephone office. Her phone line is fed
using a device called a
REG (range extender with gain). As an experiment, I had the phone guy take
the REG out of
her circuit yesterday to see if possibly it would help things. I think that
is when the
entries from above with the high R/N's are from. It didn't help so I had
him put the REG
back in the circuit.

Nothing else running in the background on her end..
