Hi... some months ago the free tone from my telephone line was a long "beeeeeeee", now it is a "beeeee beeeee beeeee". Because of this (I think) my modem and many other modems I've seen didn't recognice the "free tone" so they don't start dialing.
A work around for this is to configure the modem unchecking the option "Wait for dial tone before dialing" on Windows. So the modem dials no matter the line is free or busy.
Again, because of this, I cannot automate dialup networking to keep dialing till connected.
Does anyone know any weird AT command so the modem correctly handle the new free tone?
