What that magic number means I do not know, but dial-ups are very
susceptible to line noise. The they will drop the connection at "the
drop of a hat" - well, not quite but close :-) .
One of the things which used to cause severe line noise was a new
telephone unit which drew power from the line to recharge the capacitor
for it NVRAM for stored 'phone numbers. But this is some time
ago.....However, does anyone else use the phone at home while you are
using the modem? If so this will cause a disconnect. (Kids in the next
room are the usual culprits :-) .)
Don't resent getting old - a great many are denied the privelege.
